実験手順
To a suspension of 4-((4-fluorobenzyl)oxy)-1-(3-(methylamino)-4-nitrophenyl)pyridin-2(1H)-one (500 mg) in AcOH (30 ml) was added zinc (885 mg), and the mixture was stirred at room temperature for 1 h. The insoluble material was removed by filtration and washed with MeOH. The filtrate was concentrated, and partitioned between EtOAc, THF and saturated NaHCO3 solution. The organic layer was then washed with brine, dried over MgSO4, and concentrated. The resulting solid was collected, and washed with IPE to give the title compound (366 mg) as a brown solid.
