Procedure

A mixture of 7-nitroquinoline (0.30 g, 0.0017 mol; Specs, Inc.), 10% Pd-C (50 mg), and MeOH (20 mL) was stirred under H2 (1 atm) for 2 h. The mixture was filtered and the filtrate was concentrated to give a yellow solid (235 mg, 95%). LC-MS: 0.33 min, 145.1 (M+1). 1H NMR (DMSO-d6): 8.58 (1H, dd, J=4.4, 1.6 Hz), 8.00 (1H, dd, J=8.0, 1.2 Hz), 7.60 (1H, d, J=8.8 Hz), 7.07 (1H, dd, J=8.0, 4.4 Hz), 6.98 (1H, dd, J=8.8, 2.0 Hz), 6.93 (1H, d, J=2.0 Hz), 5.75 (s, 2H).
