Procedure

To a solution of 2-(2-{[(4-Amino-butyl)-(3,5-dimethyl-pyridin-2-ylmethyl)-amino]-methyl}-pyridin-3-yl)-propan-2-ol (0.1423 g, 0.28 mmol) in DMF (3 mL) was added 1H-pyrazole-carboxamidine hydrochloride (0.0440 g, 0.28 mmol) and DIPEA (0.29 mL, 1.68 mmol) and stirred at room temperature for 20 hours. The reaction mixture was concentrated, and purification of the crude material by column chromatography on silica gel (5:1:1 CH2Cl2-MeOH—NH4OH) followed by radial chromatography on silica gel (10:2:1 CH2Cl2-MeOH—NH4OH) provided 0.1367 g (41%) of COMPOUND 197 as a white solid. 1H NMR (CDCl3) δ 1.43-1.48 (m, 8H), 1.68-1.70 (m, 2H), 2.21 (s, 3H), 2.25 (s, 3H), 2.71-2.73 (m, 4H), 3.15-3.17 (m, 3H), 3.47 (s, 2H), 3.91 (s, 2H), 4.32 (s, 2H), 7.18-7.21 (m, 1H), 7.59-7.63 (m, 1H), 7.92-7.93 (m, 1H), 8.17 (s, 1H), 8.37-8.39 (m, 1H). 13C NMR (CDCl3) δ 18.31, 18.65, 22.77, 26.67, 31.59, 41.57, 54.09, 56.32, 61.95, 72.43, 123.57, 132.52, 132.92, 135.02, 139.67, 144.31, 146.94, 147.10, 150.68, 153.40, 158.00. ES-MS m/z 400 (M+H). Anal. Calcd. for C22H34N6O.1.9CH2Cl2.1.5H2O: C, 48.91; H, 7.01; N, 14.32. Found: C, 48.68; H, 6.83; N, 14.68.
