Patent ID: 7241886

Claim:
A process for the preparation of 10,11-dihydro-10-hydroxy-5H-dibenz[b,f]azepine-5-carboxamide comprising the steps of: reacting carbamazepine with peroxyacetic acid and a metal catalyst in a substantially inert solvent to produce 11a,10b-dihydro-6H-dibenz[b,f]oxireno[d]azepine-6-carboxamide followed by ring-opening of the 11a,10b-dihydro-6H-dibenz[b,f]oxireno[d]azepine-6-carboxamide, either by catalytic transfer hydrogenation in the presence of a hydrogen donor and metal catalyst, or alternatively by catalytic hydrogenation with gaseous hydrogen in the presence of a metal catalyst to produce the 10,11-dihydro-10-hydroxy-5H-dibenz[b,f]azepine-5-carboxamide.
