To a solution of (S)-(5-aminomethyl-2-{[(3-methyl-pyridin-2-ylmethyl)-(1-pyridin-2-yl-ethyl)-amino]-methyl}-phenyl)-methanol (0.0914 g, 0.24 mmol) in CH2Cl2 (3 mL) was added Ac2O (0.0228 mL, 0.24 mmol), Et3N (0.05 mL, 0.36 mmol), and KI (0.0033 g, 0.02 mmol), and stirred at room temperature for 18 hours. Saturated NaHCO3 (10 mL) was added and extracted with CH2Cl2 (3×30 mL), and the combined organic extracts were dried (Na2SO4), filtered, and concentrated. Purification of the crude material by column chromatography on silica gel (50:1:1 CH2Cl2-MeOH—NH4OH) provided 0.0750 g (64%) of COMPOUND 401 as a white solid. 1H NMR (CDCl3) δ 1.55 (d, 3H, J=6.6 Hz), 1.71 (s, 2H), 1.99 (s, 3H), 2.05 (s, 3H), 3.63-3.77 (m, 2H), 3.81-3.96 (m, 2H), 4.02-4.09 (m, 1H), 4.20-4.29 (m, 2H), 4.37 (d, 2H, J=5.4 Hz), 5.76 (s, 1H), 6.87 (s, 1H), 7.04-7.23 (m, 3H), 7.33-7.39 (m, 2H), 7.66 (t, 1H, J=7.5 Hz), 8.38 (d, 2H, J=3.9 Hz), 8.57 (d, 2H, J=4.2 Hz). 13C NMR (CDCl3) δ 11.93, 18.45, 23.58, 43.70, 52.43, 53.86, 58.92, 63.32, 122.57, 122.67, 124.03, 127.44, 130.86, 132.10, 132.86, 136.70, 137.05, 138.55, 142.57, 146.56, 148.93, 156.59, 161.08, 170.41.
