참여 물질

반응 단계

2-(1,3-Dioxolan-2-yl)-3-nitropyridine (10 g, 51 mmol) was suspended in ethanol (300 mL). To the mixture was added 10% Pd/C (3 g). The reaction mixture was kept at 60 psi pressure using Parr-shaker hydrogenation assembly. After completion of reaction (6 h), the reaction mixture was filtered through Celite™ and the filtrate was concentrated under reduced pressure to give 2-(1,3-dioxolan-2-yl)-3-pyridinamine as an off orange solid: 1H-NMR (CDCl3) δ: 4.4-4.0 (m, 6H), 5.8 (s, 1H), 7.2-6.9 (m, 2H), 8.0 (s, 1H).
