Versuchsvorschrift

2-Amino-6-methyl-3-nitropyridine (754 mg, 4.92 mmol) was suspended in MeOH, and 10% Pd/C was added. The mixture was stirred briskly at RT under H2 (balloon). After 4 h, the reaction was filtered through Celite®, and the filtrate was concentrated under vacuum to afford the title compound (677 mg, quantitative): 1H NMR (250 MHz, CD3OD) δ 6.82 (d, 1H), 6.36 (d, 1H), 2.25 (s, 3H).
