실험 절차

A solution of N-(1H-benzimidazol-2-ylmethyl)-N-(5,6,7,8-tetrahydroquinolin-8-yl)-ethane-1,2-diamine (0.10 g, 0.31 mmol) in isopropanol (2 mL) was treated with trimethylsilylisocyanate (60 μL, 0.44 mmol) at room temperature. The reaction was stirred 20 hours and concentrated under reduced pressure. This afforded, after column chromatography with silica gel (2:0.5:97.5 MeOH:NH4OH:CH2Cl2), {2-[(1H-benzimidazol-2-ylmethyl)-(5,6,7,8-tetrahydroquinolin-8-yl)-amino]-ethyl}-urea (67 mg, 59%). 1H NMR (CDCl3) δ 1.68 (m, 1H), 1.86 (m, 1H), 2.02 (br, 1H), 2.23 (br, 1H), 2.65 (m, 1H), 2.82 (m, 3H), 3.17 (m, 2H), 4.00 (m, 1H), 4.07 (d, 1H, J=15.0 Hz), 4.18 (d, 1H, J=15.0 Hz), 4.43 (br, 2H, NH2), 6.00 (br, 1H, NH), 7.18 (m, 3H), 7.46 (d, 1H, J=7.0 Hz), 7.45-7.70 (br, 2H), 8.55 (d, 1H, J=4.0 Hz).
