2-Aminopyridine → 6-amino-3-Pyridinepropanol

Participants

Reaction Steps

3-(6-Amino-pyridin-3-yl)-prop-2-yn-1-ol (7-2), 2.73 g (18.4 mmol) and Pd(OH)2 (0.27 g) were stirred in 30 mL EtOH (aminopyridine does not completely dissolve). Reaction was put under one atmosphere of H2 for 24 h. The reaction was filtered through a plug of celite, washed with EtOH, and concnetrated to afford the titled compound as an orange oil. 1H NMR (CDCl3) δ 7.90 (d, 1H, J=2.3 Hz), 7.31 (dd, 1H, J=2.4, 8.6 Hz), 6.43 (d, 1H, J=8.7 Hz), 4.38 (bs, 2H), 3.63 (t, 2H, J=7.5 Hz), 2.58 (t, 2H, J=7.2 Hz), 1.97 (bs, 1H), 1.82 (m, 2H).
