Reaction Steps

N-Cyclopropyl-N-{1-[4,4-bis(4-fluorophenyl)butyl]piperidin-4-yl}-3-trifluoromethylbenzenesulfonamide (34) was prepared by dissolving N-cyclopropyl-N-piperidin-4-yl-3-trifluoromethylbenzenesulfonamide (110.6 mg, 0.318 mmol) in 10 mL of DMF and followed by the addition of triethylamine (48.3 mg, 0.477 mmol) and bis(4-fluorophenyl)butyl chloride (98.2 mg, 0.350 mmol). The reaction mixture was stirred overnight at 85° C. The crude compound was purified by column chromatography on silica gel (hexane/EtOAc, 7:3) to give the title compound 34 as a yellow sticky solid. 1H NMR (CDCl3): δ 8.12 (s, 1H), 8.04 (d, 1H), 7.84 (d, 1H), 7.61 (t, 1H), 7.13 (dd, 4H), 6.94 t, 4H), 3.84 t, 2H), 2.85 (d, 2H), 2.30 (t, 2H), 1.92 (m, 7H), 1.48 (m, 2H), 1.37 (m, 2H), 0.96 (m, 2H), 0.75 (m, 2H). LC: 100%. MS (M+H+): 593.
