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]-oxadiazepines and reaction of the latter compounds with a hydrohalic acid.
