Reaction Steps

To a solution of (3-{[2-(2-isopropoxy-phenylamino)-ethylamino]-methyl}-phenyl)-piperidin-1-yl-methanone (Example 1; 0.032 g, 0.081 mmol) in DMF (0.8 mL) was added K2CO3 (0.022 g, 0.16 mmol) and iodomethane (0.03 g, 0.2 mmol), and the resulting suspension was stirred at 25° C. for 45 min. The suspension was partitioned with EtOAc (20 mL) and H2O (20 mL), and the organic layer was washed with brine (20 mL), dried (Na2SO4), filtered, and concentrated under reduced pressure. The crude residue was purified by preparative TLC (2% CH3OH/CH2Cl2) to provide a colorless oil (0.015 g, 47%). MS (ESI): mass calculated for C26H35N3O2, 409.27; m/z found, 410.5 [M+H]+, 432.4 [M+Na]+. 1H NMR (CDCl3, 400 MHz): 7.46 (d, J=7.6 Hz, 1H), 7.36-7.31 (m, 2H), 7.27-7.25 (m, 1H), 6.84 (dt, J=7.8, 1.3 Hz, 1H), 6.78 (dt, J=7.8, 1.3 Hz, 1H), 6.63 (dt, J=7.8, 1.6 Hz, 1H), 6.58 (dt, J=7.8, 1.6 Hz, 1H), 4.53 (hept, J=6.1 Hz, 1H), 3.70 (br s, 2H), 3.60 (br s, 2H), 3.31 (br s, 2H), 3.20 (t, J=6.1 Hz, 2H), 2.73 (t, J=6.1 Hz, 2H), 2.20 (s, 3H), 1.62-1.46 (m, 6H), 1.37 (d, J=6.1 Hz, 6H).
