Method for preparation of 10,11-dihydro-10-hydroxy-5H-dibenz/b,f/azepine-5-carboxamide and 10,11-dihydro-10-oxo-5H-dibenz/b,f/azepine-5-carboxamide

摘要

A process for the preparation of 10,11-dihydro-10-oxo-5H-dibenz/b,f/azepine-5-carboxamide (2) from 10,11-dihydro-10-hydroxy-5H-dibenz/b,f/azepine-5-carboxamide (1), comprising oxidising 10,11-dihydro-10-hydroxy-5H-dibenz/b,f/azepine-5-carboxamide (1) by reaction with peroxyacetic acid in the presence of a metal catalyst in a substantially inert solvent.
