Procedure

To a solution of 200 mg of N-(2-{3-((3S)-3-piperidylmethyl)amino-3-oxopropyl}amino-2-oxoethyl)-3,3,3-triphenylpropanamide monohydrochloride in 10 ml of tetrahydrofuran, 0.10 ml of 2-methylbutanal and 230 mg of sodium triacetoxyborohydrate were successively added at room temperature, followed by 2 hours' stirring at the same temperature. The reaction liquid was diluted with ethyl acetate, washed successively with saturated aqueous sodium bicarbonate solution and saturated saline solution, and dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure and the resultant residue was purified by means of silica gel column chromatography (eluting solvent: chloroform/methanol=19/1-4/1), to provide 158 mg of the title compound as a colorless solid.
