実験手順

To a solution of N1-(3,5-dimethyl-pyridin-2-ylmethyl)-N1isoquinolin-1-ylmethyl-butane-1,4-diamine (83 mg, 0.24 mmol) in CH2Cl2 (5 mL) was added Et3N (0.13 mL, 0.96 mmol) and 1H-benzoimidazole-4-carbonyl chloride (86 mg, 0.48 mmol) and the mixture was stirred for 2 d. Then it was diluted with CH2Cl2 (20 mL) and washed with saturated NaHCO3 (3×15 mL). The organic layer was dried (MgSO4), filtered, and concentrated to afford a yellow oil. Purification by radial chromatography on silica gel (1 mm plate; using CH2Cl2/MeOH/NH4OH; 50:1:1) afforded the product as a yellow oil (34 mg, 29%). 1H NMR (CDCl3) δ 1.48-1.53 (m, 2H), 1.66 (s, 6H), 1.72 (br m, 2H), 2.03 and 2.07 (s, total 3H), 2.25 and 2.27 (s, total 3H), 2.64 (t, 2H, J=7.5 Hz), 3.30 (br m, 1H), 3.40 (br m, 1H), 3.81 and 3.87 (s, total 2H), 4.21 and 4.25 (s, total 2H), 7.37-7.42 (m, 2H), 7.55-7.57 (m, 2H), 8.04-8.07 (m, 2H), 8.13-8.17 (m, 2H), 8.38 and 8.40 (s, total 1H), 9.79 (br s, 1H). 13C NMR (CDCl3) δ 18.32, 18.43, 24.42, 26.61, 27.88, 30.10, 39.57, 53.83, 54.90, 58.23, 59.54, 115.20, 121.06, 123.26, 123.88, 126.80, 127.01, 127.27, 128.13, 130.33, 132.48, 133.33, 136.67, 139.37, 141.47, 146.47, 146.58, 154.16, 159.19.
