3-{4-[3-(4-Nitrophenyl)-2-oxo-2H-pyridin-1-ylmethyl]phenyl}propionic acid ethyl ester (P7, 300 mg, 0.74 mmol) and palladium on charcoal (30 mg) were stirred at room temperature in ethanol (10 mL) under atmospheric pressure of hydrogen for 3 hours, then the reaction mixture was filtered through celite and concentrated. The crude oil was purified by chromatography on silica gel (50% v/v ethyl acetate in petroleum ether) to afford the title compound as an oil.
