반응 단계

A mixture of 2-nitro-isophthalamide (6 g, 0.028 mol) and Pd/C (0.6 g) in DMF (100 mL) was hydrogenated at RT under hydrogen bladder pressure for 16 h. The reaction mixture was filtered through celite bed, washed with DMF and filtrate was evaporated under vacuum to afford the title compound as a brown solid (yield 78%). LC-MS [178 (M−H)], 1H NMR (400 MHz, DMSO-d6): δ 7.97 (s, 2H), 7.84 (brs, 2H), 7.65 (d, J=7.76 Hz, 2H), 7.22 (brs, 2H), 6.49 (t, J=7.76 Hz, 1H).
