Procedure
Paraformaldehyde (41 mg) and 119 mg of triacetoxy sodium borohydride were added to a solution of 50 mg of 3-(2-cyanophenyl)-5-(2-pyridyl)-1-(3-aminophenyl)-1,2-dihydropyridin-2-one in 3 ml of acetic acid followed by stirring at room temperature for one night. To this was added an aqueous solution of sodium bicarbonate, the mixture was extracted with ethyl acetate, the organic layer was washed with water, dried and concentrated and the residue was purified by a silica gel column chromatography (ethyl acetate/hexane system) to give 11 mg of the title compound as a pale yellow solid.
