Procedure

A mixture of 5-methylamino-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.6 g), N,N-dimethyl-2-chloroacetamide (0.19 g) and potassium carbonate (0.22 g) is refluxed for 24 hours. The reaction solution is concentrated and water is added to the resulting residue. The mixture is 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=30:1) to give 5-[N-methyl-N-(dimethylaminocarbonylmethyl)amino]-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.05 g) as colorless amorphous.
