PROCESS FOR THE PREPARATION OF`1,4,5!-OXADIAZEPINE DERIVATIVES

摘要

A process for the preparation of [1,4,5]−oxadiazepine derivatives by reaction of N,N'−diacyl−hydrazines with 2,2'−disubstituted diethyl ethers to form 4,5−diacyl−[1,4,5]−oxadi azepines and reaction of the latter compounds with a hydrohalic acid.
