Procedure

100 mg of 10% palladium-carbon was added to 20 ml of an ethanol solution containing 546 mg of 3-nitro-1-phenyl-5-(pyridin-2-yl)-1,2-dihydropyridin-2-one, followed by stirring overnight in hydrogen atmosphere. The reaction mixture was filtered through silica gel and concentrated, to give 411 mg of the title compound.
