Procedure
To a suspension of 5-methylamino-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (3 g) in methanol (30 ml) are added potassium carbonate (1.5 g) and epichlorohydrine (5.7 ml), and the mixture is refluxed for 3 hours. The solvent is distilled off and to the resulting residue is added water and extracted three times with dichloromethane. The extract is washed with saturated saline solution and dried over magnesium sulfate. The resulting residue is purified by silica gel column chromatography (eluent; dichloromethane:methanol=80:1) to give 5-(N-methyl-N-oxiranylmethylamino)-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (C; 1.92 g) and 5-[N-methyl-N-(2-hydroxy-3-methoxypropyl)amino]-1-[4-(2-methylbenzoylamino)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine (D; 0.38 g).
