Abstract

В заявке описан способ получения соединения формулы (I)в которой R обозначает С-Салкил, путем взаимодействия соединения общей формулы (II)в которой Rи Rвсе независимо обозначают С-Салкил; или Rи Rсовместно с атомом азота, к которому они присоединены, образуют алициклический кольцевой амин, содержащий от 4 до 7 атомов углерода, или морфолиновое кольцо, с эфиром уксусной кислоты общей формулы (III)CHCOOR (III),в которой R является таким, как определено для формулы I, в присутствии основания.
