Reaction Steps

To a solution of 1-(4-fluorophenyl)-3-nitropyridin-2(1H)-one (610 mg, 2.6 mmol) in THF (50 mL) and MeOH (50 mL), were added ammonium chloride (695 mg, 13.0 mmol, EMD) and Zn dust (850 mg, 13.0 mmol, Aldrich). The reaction mixture was stirred at room temperature for 3 h, diluted with 200 mL of EtOAc and filtered through a pad of Celitee. The filtrate was concentrated in vacuo to give the desired product (530 mg, 100% yield) as a brown solid. MS(ESI+) m/z 205.29 (M+H)+.
