Reaction Steps

2-[2-(4-Methoxybenzyl)-2H-[1,2,4]triazol-3-ylmethyl]-6-nitro-1,2,3,4-tetrahydro-isoquinoline (0.5 g, 1.3 mmol) was hydrogenated in methanol (25 mL) over 10% Pd/C (0.25 g) at 50 psi (about 345 kPa) for three hours. The reaction mixture was filtered and the solvent was evaporated in vacuo. Ethyl acetate and water were added and the pH was adjusted to 10 with solid sodium carbonate. The layers were separated and the aqueous layer was extracted with additional ethyl acetate. The combined organic layers were washed with brine, dried over magnesium sulfate, filtered and evaporated in vacuo to an oil; 0.4 g, 87% yield. 1H NMR (CDCl3) δ 7.86 (s, 1), 7.18 (d, 2), 6.79 (m, 3), 6.48 (m, 2), 5.42 (s, 2), 3.76 (s, 3), 3.73 (s, 2), 3.50 (s, 2), 2.80 (m, 2), 2.69 (m, 2). IR (KBr) 1613, 1587, 1513 cm-1. Mass spectrum: m/z: 348 (M+ -1).
