Procedure

7-chloro-1-[2-methyl-4-(2-methyl benzoyl amino) benzoyl]-5 oxo-2,3,4,5-tetrahydro-1H-1-benzazepine (2 gm) was suspended in methanol (48 ml) & water (12 ml) and then added sodium borohydride (0.236 gm.) at 25° C. and the reaction mixture was stirred for 1hr. To the reaction mixture was added water (12 ml) and stirred for 2 hours at 25-30° C. The solid obtained was collected by filtration and dried to give 7-chloro-5-hydroxy-1-[2-methyl-4-(2-methylbenzoylamino) benzoyl]-2,3,4,5-tetrahydro-1H-1-benzazepine (1.70 gm).
