Reaction Steps

Sodium hydride (60% dispersion in mineral oil, 2.5 mg, 0.062 mmol) was added to a solution of 1-{3-[2-(4-chlorophenyl)-5-methyl-1H-indol-3-yl]-1-oxopropyl}-4-(2-methoxyphenyl)piperazine (Example 119, 20 mg, 0.041 mmol) in N,N-dimethylformamide (1 mL) and the mixture was stirred at room temperature for 10 min. Iodomethane (5 μl, 0.12 mmol) was added and the mixture was stirred at room temperature for 10 min. Water (25 mL) was added and the mixture was extracted with ethyl acetate. The combined organic fractions were dried (MgSO4), the solvent was evaporated under reduced pressure and the residue was purified by flash column chromatography on silica gel, eluting with hexane/ether (35:65) to give the title compound as a pale yellow foam (20 mg, 97%). 1H NMR (360 MHz, CDCl3) δ7.48-7.43 (3H, m), 7.33-7.31 (2H, m), 7.24-7.21 (1H, m), 7.11-7.02 (2H, m), 6.91-6.84 (3H, m), 3.86 (3H, s), 3.76 (2H, m), 3.53 (3H, s), 3.38 (2H, m), 3.04 (2H, m), 2.94 (2H, m), 2.77 (2H, m), 2.57 (2H, m), and 2.49 (3H, s). m/z (ES+) 502, 504 (M+1).
