Procedure

To a solution of (5-aminomethyl-2-{[(5-chloro-3-methyl-pyridin-2-ylmethyl)-(1-methyl-1-pyridin-2-yl-ethyl)-amino]-methyl}-phenyl)-methane (0.0966 g, 0.23 mmol) in CH2Cl2 (3 mL) was added Ac2O (0.0213 mL, 0.23 mmol), Et3N (0.05 mL, 0.35 mmol), and KI (0.0038 g, 0.02 mmol), and stirred for 18 hours at room temperature. Saturated NaHCO3 (10 mL) was added and extracted with CH2Cl2 (3×20 mL). The combined organic extracts were dried (Na2SO4), filtered, and concentrated. Purification of the crude material by column chromatography on silica gel (100:1:1 CH2Cl2-MeOH—NH4OH) provided 0.0573 g (52%) of COMPOUND 403 as a white solid. 1H NMR (CDCl3) δ 1.61 (s, 6H), 2.00 (s, 3H), 2.08 (s, 3H), 3.69 (s, 2H), 3.90 (s, 2H), 4.30 (d, 2H, J=5.4 Hz), 4.53 (s, 2H), 5.65 (s, 1H), 6.69 (s, 1H), 6.94 (d, 1H, J=7.5 Hz), 7.03-7.09 (m, 3H), 7.17 (s, 1H), 7.54 (t, 1H, J=7.8 Hz), 7.75 (d, 1H, J=8.1 Hz), 8.04 (s, 1H), 8.47 (d, 1H, J=6.0 Hz). 13C NMR (CDCl3) δ 18.72, 23.66, 24.47, 43.62, 51.37, 53.92, 63.30, 64.75, 122.16, 122.99, 127.27, 129.31, 130.85, 131.46, 132.38, 136.22, 137.30, 138.04, 138.13, 141.45, 144.53, 147.99, 156.81, 165.70, 170.29.
