Procedure

To a solution of 7-chloro-5-(2-aminoethyl)-1-[6-(2-chlorobenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.5 g)in methanol (2,0 ml) is added 37% formalin (1.4 ml), and thereto is added sodium cyanoborohydride (0.2 g), and further thereto is added with stirring acetic acid (0.9 ml) at 10° C., and the mixture is stirred at room temperature for 3 hours. The mixture is poured into ice-water, and the mixture is made basic with potassium carbonate, and the mixture is extracted with dichloromethane. The extract is washed with water, dried over magnesium sulfate, and evaporated under reduced pressure to remove the solvent. The residue is purified by silica gel column chromatography to give 7-chloro-5-(2-dimethylaminoethyl)-1-[6-(2-chlorobenzoylamino)nicotinoyl]-2,3,4,5-tetrahydro-1H-benzazepine (0.37 g) as colorless amorphous.
