実験手順

To a warm (70° C.), stirred, solution of N-(3,5-Dimethyl-pyridin-2-ylmethyl)-N-isoquinolin-1-ylmethyl-N′-methyl-butane-1,4-diamine (0.204 g, 0.56 mmol) and DIPEA (0.59 mL, 3.39 mmol) in DMF (5 mL) was added freshly prepared imidazole-1-carboxylic acid (1H-imidazol-2-yl)-amide (2 equivs). After 1.5 hours, the mixture was cooled to room temperature and concentrated under reduced pressure. The residue was dissolved in CH2Cl2 (50 mL) and washed with water (5×10 mL). The organic phase was dried (Na2SO4) and concentrated. Purification of the crude material by column chromatography on silica gel (20:1:1 CH2Cl2-MeOH—NH4OH) provided 234 mg (86%) of COMPOUND 156 as a white solid. 1H NMR (CDCl3) δ 1.26-1.34 (m, 2H), 1.42-1.48 (m, 2H), 2.09 (s, 3H), 2.28 (s, 3H), 2.58 (t, 2H, J=7.5 Hz), 2.74 (s, 3H), 3.10 (t, 2H, J=7.5 Hz), 3.80 (s, 2H), 4.17 (s, 2H), 6.68 (s, 2H), 7.24-7.26 (m, 1H), 7.35-7.40 (m, 1H), 7.52-7.60 (m, 2H), 7.73 (d, 1H, J=8.1 Hz), 7.97 (d, 1H, J=8.7 Hz), 8.22 (s, 1H), 8.41 (d, 1H, J=5.7 Hz); 13C NMR (CDCl3) δ 18.33, 18.40, 23.93, 25.82, 34.90, 48.89, 54.57, 59.86, 59.96, 120.82, 126.71, 126.92, 127.20, 128.12, 130.13, 132.27, 133.15, 136.62, 139.08, 141.76, 145.16, 146.87, 154.33, 156.14, 159.39; ES-MS m/z 472 (M+1).
