실험 절차

2-Amino-5-(4-fluorophenyl)-3-nitropyridine (200 mg, 0.86 mmol) was suspended in a mixture of methanol (5 mL), ethyl acetate (5 mL), tetrahydrofuran (5 mL) and triethylamine (2 mL). After addition of 10% palladium carbon (100 mg), the mixture was stirred at room temperature for 1.5 hours under a hydrogen atmosphere. The reaction mixture was filtered, and the filtrate was concentrated in vacuo. The residue was purified by silica gel column chromatography (C-300, chloroform:methanol=50:1) to give the title compound (76 mg, 44%) as a white solid.
