Procedure

To a solution of 5-methylamino-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.6 g) in dichloromethane is added triethylamine (0.24 ml). Subsequently, thereto is added benzoyl chloride (0.2 ml) under ice-cooling, and the temperature thereof is raised to room temperature, and the mixture is stirred overnight. Water is added to the reaction solution and extracted three times with dichloromethane. The extract is 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), and recrystallized from ethanol to give 5-(N-methyl-N-benzoylamino)-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.64 g) as colorless needles, m.p. 248-249° C.
