Reaction Steps

A mixture of 5-benzyloxypyrrolo[3,4-b]pyridine (Compound 7f, 1.38 g, 6.15 mmol), 5% Pd/C (0.30 g), and absolute ethanol (25 mL) was shaken under a hydrogen atmosphere (3 atm) for 30 minutes. The resulting mixture was filtered through diatomaceous earth (Celite (trademark)), and the filtrate was evaporated under reduced pressure. The residual solid was triturated in ethyl ether to yield Compound 7i (0.80 g, 5.96 mmol, 97%) as an off-white crystalline solid: mp, 280.0°-282.0° C.: IR (KBr) 1,640, 1,615, 1,605, 1,455, 1,430, 1,400, 1,380, 1,365 cm-1 ; 1H NMR (DMSO-d6) δ 11.4 (br m, 2H), 7.56 (d, J=9.7 Hz, 1H), 7.16 (d, J=3.1 Hz, 1H), 6.01-5.93 (m, 2H); 13C NMR (DMSO-d6) 162.0, 131.9, 127.9, 125.0, 118.2, 112.2, 94.5; LRMS (m/z, relative intensity) 135 (41), 134 (M+, 100), 106 (66), 105 (42), 79 (59), 53 (31), 52 (52). Anal. calcd. for C7H6N2O: C, 62.68; H, 4.51; N, 20.88; found: C, 62.40; H, 4.40; N, 20.76.
