40 g 7 - (2 - Hydroxy - 3 - 2' - 3",4" - dihydroxyphenyl-2'-oxoäthyl-benzylamino-propyl)-theophyllin-hydro- chlorid werden in 1280 cm3 50%igem wäßrigem Methylalkohol warm gelöst und unter Zusatz von 3,5 g 10%igem Palladium-Kohle-Katalysator bei 50° C hydriert. Nachdem nach Aufnahme von etwa 1 Mol H2 die Wasserstoffaufnahme fast zum Stillstand gekommen ist, filtriert man und hydriert unter Zugeben von weiteren 3,5 g Katalysator zu Ende. Anschließend wird filtriert und im Vakuum eingedampft. Man kocht den Rückstand mit Äthylalkohol, wobei Kristallisation erfolgt. Nach dem Abkühlen wird abgesaugt und getrocknet. Man erhält 26,9 g des Hydrochlorids vom Schmelzpunkt 209 bis 21Γ C.40 g of 7 - (2 - hydroxy - 3 - 2 '- 3 ", 4" - dihydroxyphenyl-2'-oxoethyl-benzylamino-propyl) -theophylline-hydrochloride are dissolved warm in 1280 cm 3 of 50% aqueous methyl alcohol and hydrogenated at 50 ° C. with the addition of 3.5 g of 10% palladium-carbon catalyst. After the uptake of hydrogen has almost come to a standstill after the uptake of about 1 mol of H 2, the mixture is filtered and hydrogenated to the end with the addition of a further 3.5 g of catalyst. It is then filtered and evaporated in vacuo. The residue is boiled with ethyl alcohol, whereupon crystallization occurs. After cooling, it is filtered off with suction and dried. 26.9 g of the hydrochloride with a melting point of 209 to 21 ° C. are obtained.

Herstellung des AusgangsketonsProduction of the starting ketone

Zu einer Lösung von 66,0 g 7-(2-Hydroxy-3-benzylamino-propyl)-theophyllin in 195 cm3 25%igem Äthylalkohol wird im Stickstoffstrom unter Rühren bei 80° C Wasserbadtemperatur eine Lösung von 17,9 g S^-Dihydroxy-cu-chlor-acetophenon in 100 cm3 Äthylalkohol innerhalb von 2 Stunden zugetropft. Man rührt noch 2 Stunden bei dieser Temperatur, säuert mit alkoholischer Salzsäure an und versetzt mit 870 cm3 Äthylalkohol. Nach 24 Stunden wird das ausgefallene Hydrochlorid des überschüssigen 7-(2-Hydroxy-3-benzylamino-propyl)-theophyllins abgesaugt (35,3 g) und das Filtrat eingedampft. Der Rückstand wird mit Aceton aufgenommen und das nach einigem Stehen auskristallisierte 7-(2-Hydroxy-3-2'-3",4"-dihydroxyphenyl - 2' - oxoäthyl - benzylamino - propyl)-theophyllin-hydrochlorid abgesaugt. Zur Reinigung wird mit Äthanol ausgekocht. Ausbeute: 40,0 g; Schmelzpunkt: 185 bis 188°C.To a solution of 66.0 g of 7- (2-hydroxy-3-benzylamino-propyl) -theophylline in 195 cm 3 of 25% ethyl alcohol, a solution of 17.9 g of S ^ is added in a stream of nitrogen with stirring at 80 ° C. water bath temperature Dihydroxy-cu-chloro-acetophenone in 100 cm 3 of ethyl alcohol was added dropwise within 2 hours. The mixture is stirred for a further 2 hours at this temperature, acidified with alcoholic hydrochloric acid and treated with 870 cm 3 of ethyl alcohol. After 24 hours, the precipitated hydrochloride of the excess 7- (2-hydroxy-3-benzylamino-propyl) -theophylline is filtered off with suction (35.3 g) and the filtrate is evaporated. The residue is taken up in acetone and the 7- (2-hydroxy-3-2'-3 ", 4" -dihydroxyphenyl - 2 '- oxoethyl - benzylamino - propyl) theophylline hydrochloride which has crystallized out after standing for a while is filtered off with suction. For cleaning, it is boiled with ethanol. Yield: 40.0 g; Melting point: 185 to 188 ° C.
