実験手順
3-Methoxy-2-nitrobenzamide (7.0 g, 0.038 mol) was dissolved in ethanol (150 ml) and the solution stirred with Raney nickel catalyst (0.5 g) under a hydrogen atmosphere at 50 p.s.i. (3.45 bar) for 4 hours. The catalyst was removed by filtration and the solvent removed by evaporation under vacuum to give the title compound, after crystallization from ethyl acetatehexane, as a colorless solid (6.3 g, 83%), m.p. 140°-141° C. Found: C,58.03; H,6.06; N,16.65. C8H10N2O2 requires C,57.82; H,6.07; N,16.86%.
