1-(2-Нитрилофенокси)-2 - окси-3-этиламинопропан менее токсичен и более эффективен по своему физиологическому действию, чем известный 1-(1-нафтокси)-2-окси-3-алкиламинопропан . Синтезированное соединение содержит ассиметрический атом углерода и может присутствовать как в виде рацемата, так и в виде оптических антиподов; последние можно получить, использу оптические исходные соединени , или разделением рацемата такими кислотами, как дибензоилвинна или бромкамфарна .1- (2-Nitrilophenoxy) -2 - hydroxy-3-ethylaminopropane is less toxic and more effective in its physiological effect than the known 1- (1-naphthoxy) -2-hydroxy-3-alkylaminopropane. The synthesized compound contains an asymmetric carbon atom and may be present both as a racemate and as an optical antipode; the latter can be obtained using optical starting compounds, or by separating the racemate with acids such as dibenzoyl-twin or bromo-camphor.

Объединенные водные экстракты подщелачивают NaOH и выдел ющеес масло поглощают эфиром . Раствор эфира промывают, сушат и выпаривают . Остаток раствор ют в спирте, подкисл ют спиртовой сол ной кислотой и гидрохлорид кристаллизуют при добавлении эфира. Температура плавлени полученного продукта 130-133,5°С.Example. A mixture of 3.05 g (0.01 mol) of N-isopropyl — N-ethyl-2-hydroxy-3- (2-nitrylphenoxy) propyl urea, 20 ml of tetralin, 100 ml of lithium chloride is heated for 1.5 hours in an oil bath and after diluting with 30 mg of ether, extract (2x15 ml) with 1N. HCl solution. The combined aqueous extracts are alkalized with NaOH and the liberated oil is taken up in ether. The ether solution is washed, dried and evaporated. The residue is dissolved in alcohol, acidified with alcoholic hydrochloric acid, and the hydrochloride is crystallized by the addition of ether. The melting point of the obtained product is 130-133.5 ° C.
