Procedure

Sodium triacetoxyborohydride (10 mg) was added to a solution of 10 mg of 3-(2-cyanophenyl)-5-(2-formylthiophen-3-yl)-1-phenyl-1,2-dihydropyridin-2-one in 2 ml of tetrahydrofuran and the mixture was stirred for 1 hour. A 10% aqueous solution of sodium carbonate was added thereto, the mixture was extracted with ethyl acetate and the organic layer was washed with water and a saturated saline solution and dried over magnesium sulfate. The solvent was concentrated in vacuo and the residue was purified by an NH silica gel column chromatography to give 8 mg of the title compound as white powder.
