Procedure

Slowly add 1-(1H-Indol-3-yl)-2-piperidin-1-yl-ethanone (199 mg, 0.821 mmol, 1.0 eq) as a 2 ml DMF solution to a flask under N2 containing sodium hydride (36 mg, 60 wt % on oil, 0.903 mmol, 1.1 eq) in 2 ml DMF solution. Stir solution for 5 minutes. Slowly add 4-(4-Fluoro-benzylcarbamoyl)-benzenesulfonyl chloride (296 mg, 0.903 mmol, 1.1 eq) as a 3 ml DMF solution. Stir reaction for 18 hours at room temperature. Strip reaction of solvent and purify on silica gel chromatography to give N-(4-Fluoro-benzyl)-4-[3-(2-piperidin-1-yl-acetyl)-indole-1-sulfonyl]-benzamide (249 mg, 57% yield). Mass Spectrum (m/e): 534 (MH+).
