실험 절차
(4-Chloro-but-2-enyl)-carbamic acid tert-butyl ester (1.81 g, 7.47 mmol), potassium iodide (59 mg, 0.36 mmol) and diisopropylethylamine (1.80 mL, 10.3 mmol) were added to a solution of 2-[(5,6,7,8-tetrahydroquinolin-8-ylamino)-methyl]-benzimidazole-1-carboxylic acid tert-butyl ester (2.57 g, 6.79 mmol)) in acetonitrile (70 mL) and warmed to 60° C. and stirred for 17 h under nitrogen. The solvent was removed in vacuo. The residue was dissolved in methylene chloride (100 mL) and washed with brine (100 mL). The aqueous layer was extracted with methylene chloride (2×150 mL). The combined organic layers were dried (Na2SO4) and concentrated. The crude mixture was purified by column chromatography on silica gel (150 g) to afford 2-{[(S)-((Z)-4-tert-butoxycarbonylamino-but-2-enyl)-5,6,7,8-tetrahydro-quinolin-8-yl-amino]-methyl}-benzimidazole-1-carboxylic acid tert-butyl ester (5.99 g, 88%) as a white foamy solid. 1H NMR (CDCl3) δ 1.43 (s, 9H), 1.72 (s, 9H), 1.95-2.08 (m, 4H), 2.09-2.20 (m, 1H), 2.61 (d, 1H, J=16.2 Hz), 3.28 (dd, 1H, J=14.1, 5.4 Hz), 3.62 (dd, 1H, J=13.7, 7.2 Hz), 3.69-3.85 (m, 2H), 4.29 (dd, 1H, J=9.2, 6.6 Hz), 4.42 (d, 1H, J=14.9 Hz), 4.48 (d, 1H, J=14.9 Hz), 5.43-5.63 (m, 2H), 6.19 (s, 1H), 6.87 (dd, 1H, J=7.5, 4.8 Hz), 7.17 (d, 1H, J=7.7 Hz), 7.23-7.28 (m, 1H), 7.65-7.71 (m, 1H), 7.75-7.80 (m, 1H), 8.34 (d, 1H, J=4.4 Hz).
