Der Rückstand wurde unter reduziertem Druck destilliert und ergab dabei l-Brom-4-p-nitrophenoxybutan; Kp.oo6144 bis 146° C.Remove p-nitrophenol. The ethereal solution was washed with water, dried over potassium carbonate, filtered and evaporated. The residue was distilled under reduced pressure to give 1-bromo-4-p-nitrophenoxybutane; Bp o 6 144 to 146 ° C.
Eine Lösung dieses Äthers (62 g) in einer Lösung von Dimethylamin in Äthanol (154 g; 35% Gewicht/ Gewicht) wurde bei 800C 6 Stunden lang in einem Autoklav erhitzt. Das resultierende Reaktionsgemisch wurde auf einem Dampfbad eingedampft. Der Rückstand wurde in 4 η-Salzsäure im Ubersehuß aufgelöst, und die nicht basischen Nebenprodukte wurden mit Äther entfernt. Bei Zusatz von Ammoniak im Ubersehuß zu der Säureschicht wurde ein öl ausgefällt, das mit Äther extrahiert wurde. Die ätherische Lösung wurde mit Wasser gewaschen, über Kaliumcarbonat getrocknet, filtriert und eingedampft. Das restliche öl wurde wiederum in 4 η-Salzsäure im Ubersehuß aufgelöst, und die Lösung wurde unter reduziertem Druck eingedampft. Der Rückstand wurde zweimal aus Methanol auskristallisiert und ergab dabei 1-Dimethylamino-4-p-nitrophenoxybutanhydrochlorid; F. =- 1730C. Die reine Base wurde mit Ammoniak im Ubersehuß regeneriert und mit Äther als ein gelbes öl isoliert, das anschließend erstarrte; F. - 200C.A solution of this ether (62 g) in a solution of dimethylamine in ethanol (154 g; 35% weight / weight) was heated in an autoclave at 80 ° C. for 6 hours. The resulting reaction mixture was evaporated on a steam bath. The residue was dissolved in excess 4η hydrochloric acid and the non-basic by-products were removed with ether. When excess ammonia was added to the acid layer, an oil was precipitated and extracted with ether. The ethereal solution was washed with water, dried over potassium carbonate, filtered and evaporated. The remaining oil was again dissolved in excess 4η hydrochloric acid and the solution was evaporated under reduced pressure. The residue was crystallized twice from methanol to give 1-dimethylamino-4-p-nitrophenoxybutane hydrochloride; F. = - 173 0 C. The pure base was regenerated with ammonia in Ubersehuß and with ether as a yellow oil is isolated which solidified subsequently; F. - 20 0 C.
Einer Lösung von 5 g dieser Base in 10 ml Aceton wurden 4 g Benzylbromid hinzugesetzt, wobei das Gemisch heiß wurde. Es wurde schließlich 30 Minuten lang unter Rückfluß erhitzt. Beim Abkühlen schieden sich rasch Kristalle aus, welche aufgesammelt und aus Isopropanol umkristallisiert wurden. Man erhielt N-Benzyl-N,N-dimethyl-N-4-p-nitrophenoxybutylammoniumbromid; F. = 152°C.4 g of benzyl bromide were added to a solution of 5 g of this base in 10 ml of acetone, the Mixture got hot. It was finally refluxed for 30 minutes. When cooling down Crystals quickly separated out, which were collected and recrystallized from isopropanol. N-benzyl-N, N-dimethyl-N-4-p-nitrophenoxybutylammonium bromide was obtained; M.p. = 152 ° C.
N-S-Chlorthienyl-NjN-dimethyl-N^-p-nitrophenoxybutylammoniumjodid N-S-Chlorothienyl-NjN-dimethyl-N ^ -p -nitrophenoxybutylammonium iodide
4,1 g 5-Chlorthienylchlorid (5-Chlor-2'-chlormethylthiophen) wurden in einer Lösung von 3,52 g Natriumjodid in 10 ml Aceton hinzugesetzt; das Gemisch wurde erwärmt. Nach V2Stündigem Stehenlassen wurde das ausgefällte Natriumchlorid abfiltriert und mit ein wenig frischem Aceton gewaschen. Dem Filtrat wurden 5,7 g l-Dimethylamino-4-p-nitrophenoxybutan hinzugesetzt, und die Lösung wurde 30 Minuten unter Rückfluß erhitzt. Nach dem Abkühlen wurden die ausgeschiedenen Kristalle abfiltriert und mit Äthylacetat gewaschen. Das verbleibende N-S-Chlorthienyl-N^-dimethyl-N^-p-nitrophenoxybutylammoniumjodid wurde aus Methanol auskristallisiert; F. = 139 bis 14O0C.4.1 g of 5-chlorothienyl chloride (5-chloro-2'-chloromethylthiophene) were added to a solution of 3.52 g of sodium iodide in 10 ml of acetone; the mixture was heated. After standing for two and a half hours, the precipitated sodium chloride was filtered off and washed with a little fresh acetone. To the filtrate was added 5.7 g of 1-dimethylamino-4-p-nitrophenoxybutane, and the solution was refluxed for 30 minutes. After cooling, the precipitated crystals were filtered off and washed with ethyl acetate. The remaining NS-chlorothienyl-N ^ -dimethyl-N ^ -p-nitrophenoxybutylammonium iodide was crystallized from methanol; F. = 139 to 14O 0 C.
40 5 Stunden lang auf einem Dampfbad erhitzt. Nach dem Abkühlen wurde das Gemisch filtriert, und der Rückstand wurde mit frischem Benzol gewaschen. Filtrat und Waschlaugen wurde miteinander mit 4 η-Salzsäure im Ubersehuß geschüttelt, wobei sich festes 1 -Benzylamino^-p-chlorphenoxyäthanhydrochlorid ausschied. Nach dem Abfiltrieren und Umkristallisieren aus 10% Äthanol enthaltendem Isopropanol erhielt man farblose Nadeln; F. -= 190 bis 191°C. 40 heated on a steam bath for 5 hours. After cooling, the mixture was filtered and the residue was washed with fresh benzene. The filtrate and wash liquors were shaken together with excess 4 η hydrochloric acid, solid 1 -benzylamino ^ -p-chlorophenoxyethane hydrochloride precipitated out. After filtering off and recrystallization from isopropanol containing 10% ethanol, colorless needles were obtained; F. - = 190 to 191 ° C.
5,96 g dieses Hydrochlorids wurden mit wäßriger Ammoniaklösung behandelt und ergaben dabei die freie Base, welche mit Äther isoliert wurde. Einer Schlämme von 5,3 g Natriumcarbonat in 15 ml Methanol setzte man zunächst diese Base und dann 14,5 g Methyljodid hinzu. Das resultierende Gemisch wurde 2 Stunden lang unter Rückfluß erhitzt und heiß filtriert. Nach dem Zusatz von Äther zu dem Filtrat erhielt man N-Benzyl-N-2-p-chlorphenoxyäthyl-N,N-dimethylammoniumjodid, das aus Äthanol umkristallisiert wurde; F. = 166°C.5.96 g of this hydrochloride were treated with aqueous ammonia solution and gave the free base, which was isolated with ether. A slurry of 5.3 g of sodium carbonate in 15 ml This base and then 14.5 g of methyl iodide were added to methanol. The resulting mixture was refluxed for 2 hours and filtered hot. After adding ether to the The filtrate was N-benzyl-N-2-p-chlorophenoxyethyl-N, N-dimethylammonium iodide, which was recrystallized from ethanol; M.p. = 166 ° C.
N-Benzyl-N-2-p-chlorphenoxyäthyl-N-äthyl-N-methylammonium-p-toluolsulfonat N-Benzyl-N-2-p-chlorophenoxyethyl-N-ethyl-N-methylammonium-p-toluenesulfonate
Ein Gemisch aus 20 g l-Brom-2-p-chlorphenoxyäthan und 22 g Benzylmethylamin wurde auf 700C erwärmt, wobei eine schnelle exotherme Reaktion erfolgte. Nach dem Abkühlen wurde die halbfeste Masse in verdünnter Salzsäure im Ubersehuß aufgelöst, worauf die Lösung mit Äther gewaschen wurde. Die Behandlung mit Natriumhydroxyd, die Extraktion mit Äther und das Eindampfen der getrockneten Lösung ergaben ein basisches öl, das durch fraktionierte Destillation in Benzylmethylamin und 1-Benzylmethylamin - 2 - ρ - chlorphenoxyäthan geschieden wurde; Kp.0,1 1580C.A mixture of 20 g of 1-bromo-2-p-chlorophenoxyethane and 22 g of benzylmethylamine was heated to 70 ° C., a rapid exothermic reaction taking place. After cooling, the semisolid mass was dissolved in excess hydrochloric acid, whereupon the solution was washed with ether. Treatment with sodium hydroxide, extraction with ether and evaporation of the dried solution gave a basic oil which was separated into benzylmethylamine and 1-benzylmethylamine - 2 - ρ - chlorophenoxyethane by fractional distillation; Bp 0.1 158 0 C.
5 g dieser Base und eine gleiche Menge Äthylp-toluolsulfonat wurden 3 Stunden lang in 50 ml siedendem Aceton erhitzt. Beim Abkühlen und Zusatz von Äther wurde N-Benzyl-N-2-p-chlorphenoxyäthyl-N-äthyl-N-methylammonium-p-toluolsulfonat ausgefällt, das aus Äthylacetat auskristallisierte und dabei farblose Blättchen bildete; F. = 121 bis 122 C.5 g of this base and an equal amount of ethyl p-toluenesulfonate were heated in 50 ml of boiling acetone for 3 hours. When cooling and adding ether became N-benzyl-N-2-p-chlorophenoxyethyl-N-ethyl-N-methylammonium-p-toluenesulfonate precipitated, which crystallized from ethyl acetate and thereby formed colorless leaflets; F. = 121 to 122 C.
