Procedure
A solution of 3-(2-bromo-3-oxocyclohex-1-enyl)-hexahydro-1-methylazepin-2-one (6 g) in chloroform (60 ml) was treated with 48% HBr in acetic acid (1 ml). After 4 hours, NMR indicated completion. Aqueous ammonia was added and the organic solvent removed under reduced pressure to yeild the title compound as a crystalline solid, m.p. 192°-3° (EtOAc).
