Procedure
Sodium hydride (60% dispersion in mineral oil, 13 mg, 0.3 mmol) was added to a solution of 1-{3-[2-(5-chloro-4-chlorophenyl)-1H-indol-3-yl]-1-oxopropyl}-4-(2-methoxyphenyl)piperazine (Example 85, 52 mg, 0.1 mmol) in N,N-dimethylformamide (1 mn) and the mixture was stirred at room temperature for 5 min. Methanesulfonyl chloride (10 μl, 15 mg, 0.13 mmol) was added and the mixture was stirred at room temperature for 10 min. Further sodium hydride (60% dispersion in mineral oil, 50 mg, 1.2 mmol) and methanesulfonyl chloride (20 μl, 30 mg, 0.26 mmol) were added and the mixture was stirred at room temperature for 10 min. Saturated aqueous ammonium chloride (10 mL) was added and the mixture was extracted with ethyl acetate. The combined organic fractions were washed with aqueous ammonium chloride (10%, 10 mL) dried (Na2SO4) and the solvent was evaporated under reduced pressure. The residue was purified by flash column chromatography on silica gel, eluting with hexane/ether (50:50) to give the title compound as a colorless glass (30 mg, 51%). 1H NMR (360 MHz, CDCl3) δ8.04 (1H, d, J 8.8 Hz), 7.62 (1H, d, J 2.1 Hz), 7.45 (2H, d, J 8.5 Hz), 7.37 (2H, d, J 8.5 Hz), 7.36 (1H, dd, J 8.8, 2.1 Hz), 7.03 (1H, t, J 7.7 Hz), 6.94-6.85 (3H, m), 3.87 (3H, s), 3.75 (2H, m), 3.38 (2H, m), 2.98-2.86 (6H, m), 2.81 (3H, s), and 2.45 (2H, m). m/z (ES+) 586, 588 (M+1).
