Description
Изобретение относитс к области получени соединений, которые могут найти применение в качестве физиологически активных веществ.The invention relates to the field of the preparation of compounds which can be used as physiologically active substances.
Предлагаетс способ получени 3- (а-фенил-у-алкоксипроиан ) -оксазолидина, заключающийс в том, что 1-фенил-1-(|3-оксиэтиламино)-3-алкоксипропан , например 1-фенил-1-(р-оксиэтиламино ) -3-метоксипропан, подвергают взаимодействию с параформальдегидом при температуре кипени реакционной массы при непрерывном удалении воды циркул цией беизола, с последующим выделением полученного продукта известным способом. Выход продукта составл ет 80%.A method for the preparation of 3- (a-phenyl-y-alkoxyproian) -oxazolidine is proposed, which consists in that 1-phenyl-1- (3-hydroxyethylamino) -3-alkoxypropane, for example 1-phenyl-1- (p-hydroxyethylamino ) -3-methoxypropane, is reacted with paraformaldehyde at the boiling point of the reaction mixture with continuous removal of water by circulating with Beisol, followed by isolating the resulting product in a known manner. The product yield is 80%.
Пример. Синтез 3-(а-фенил- -метоксипропан )-оксазолидина (Н СНз). Смесь 75,24 г (0,30 г моль) -фенил-1-(р-оксиэтиламино )-3-метоксипропана (К СНз); т. кип. 141-143°С (3 мм); df 1,0480: пс° 1,5230, 15 г (0,5 г моль) параформа и 250 мл безводного бензола нагревают 4 час при иеремешивании и циркул ции бензола. При этом выдел етс 8 мл воды. Реакционную смесь разлагают водой , экстрагируют бензолом (два раза ио 50 мл). Бензольный экстракт последовательно промывают 10%-ным водным раствором NaOH (два раза) и водой. После сушки (над КзСОз) и отгонки растворител разгонкой выдел ют 57 г (71,5%) 3-(a-фeнил-Y-мeтoкcипропан )-оксазолидина (К СНз). Веществопрозрачна маслообразна жидкость со снецифическим аминиым запахом; т. кип. 136- 138°С (5 мм рт. ст.); df 1,0580; По 1,5180; MRo найдено 63,30, MRo вычислено 63,79.Example. Synthesis of 3- (a-phenyl-methoxypropane) -oxazolidine (H CH3). A mixture of 75.24 g (0.30 g mol) -phenyl-1- (p-hydroxyethylamino) -3-methoxypropane (K CH 3); m.p. 141-143 ° C (3 mm); df 1.0480: ps: 1.5230, 15 g (0.5 g mol) of paraform and 250 ml of anhydrous benzene are heated for 4 hours with stirring and circulation of benzene. This releases 8 ml of water. The reaction mixture was decomposed with water, extracted with benzene (twice with 50 ml). The benzene extract is successively washed with a 10% aqueous solution of NaOH (twice) and water. After drying (over CsSO3) and distilling off the solvent by distillation, 57 g (71.5%) of 3- (a-phenyl-Y-methoxypropane) -oxazolidine (K CH3) was isolated. The substance is a translucent, oily liquid with a crude amino-like odor; m.p. 136-138 ° C (5 mm Hg. Art.); df 1.0580; 1.5180 each; MRo found 63.30, MRo calculated 63.79.
