Reaction Steps

A solution of 1-(phenylsulfonyl)-4-piperazin-1-yl-1H-indole (71 mg, 0.18 mmol) in tetrahydrofuran is treated sequentially with benzyl bromide (21 μl) and triethyl-amine (75 μl), shaken at room temperature for 16 hr and concentrated in vacuo to give a residue. The residue is purified by RP-HPLC to give the title product, 37 mg, identfied by HPLC and mass spectral analyses (2.81 min; 432 M+H) using the LCMS conditions described in Table I.
