실험 절차

To 0.5 mL of Raney Nickel in water was added a solution of 2-{[(2-cyano-4-methoxycarbonyl-benzyl)-(5,6,7,8-tetrahydroquinolin-8-yl)-amino]-methyl}-benzimidazole-1-carboxylic acid tert-butyl ester (0.55 g, 1 mmol) in methanol (25 mL). The solution was then saturated with ammonia gas for 10 minutes. The reaction vessel was then shaken vigorously under an atmosphere of hydrogen (40 psi) for 16 hours. The mixture was filtered through a celite pad and the filtrate concentrated under reduced pressure. The crude residue was purified by column chromatography (88:12 CH2Cl2:MeOH) to afford to give the amide (0.20 g, 36%). 1H NMR (CDCl3) δ1.73 (m, 1H), 2.01 (m, 2H), 2.35 (m, 1H), 2.85 (m, 2H), 3.88 (t, 2H, J=15.9 Hz), 4.16 (m, 1H), 4.21 (d, 1H, J=9.6 Hz), 4.26 (d, 1H, J=7.8 Hz), 5.71 (br, 1H, NH), 6.12 (br, 1H, NH), 7.19 (m, 3H), 7.46 (d, 1H, J=7.8 Hz), 7.55 (br, 2H), 7.80 (d, 1H, J=8.1 Hz), 7.87 (d, 1H, J=8.1 Hz), 7.96 (s, 1H), 8.64 (dd, 1H, J=4.5 Hz). 13C NMR (CDCl3) δ21.71 29.44, 49.92, 53.09, 61.84, 112.81, 117.49, 122.30 (4C), 122.97, 130.44 (2C), 131.98, 132.32, 133.56, 135.37, 138.05 (2C), 147.13, 147.29, 155.27, 156.87, 167.82.
