PROCESS FOR THE PREPARATION OF 5-ARYL-4-ARYLTHIO-1,3,4,5-TETRAHYDRO-2H-1-BENZAZEPIN-2-ONES

摘要

A process for the preparation of 5-aryl-4-arylthio-1,3,4,5-tetrahydro-2H-1-benzazepin-2-ones according to which N-arylamides of styryl acetic acids are subjected to interaction with arylsulphenyl chlorides in acetic acid at room temperature in the presence of lithium perchlorate followed by separation of desired products by conventional methods.
