Procedure

To a solution of 5-(thiomorpholinocarbonylmethoxy)-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.40 g) in dichloromethane (40 ml) is added 80% m-chloroperbenzoic acid (175 mg) with stirring at -8° C., and the mixture is stirred at -8° C. for 1 hour. To the reaction solution is added 20% aqueous sodium hydrogensulfite solution (40 ml) and the mixture is stirred at room temperature for 30 minutes. The dichloromethane layer is collected, washed with saturated saline solution and dried over magnesium sulfate. The solvent is distilled off and the resulting residue is purified by silica gel column chromatography (eluent; dichloromethane:methanol=20:1) to give 5-[(1-oxothiomorpholino)carbonylmethoxy]-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.32 g) as colorless amorphous.
