One-pot synthesis of 2-substituted 4-aryl-4,5-dihydro-3,1-benzoxazepines from 2-(2-Aminophenyl)-1-arylethanols via dehydration of the corresponding amides

An efficient method for the preparation of 2-substituted 4-aryl-4,5-dihydro-3,1-benzoxazepine derivatives under mild conditions has been developed. The reaction of 2-(2-aminophenyl)ethanols 1 with acid chlorides in the presence of excess Et3N in THF at room temperature gave the corresponding N-acylated intermediates 2, which were dehydrated by treatment with POCl3 to give 2-substituted 4-aryl-4,5-dihydro-3,1- benzoxazepines 3 in a one-pot reaction.
