Procedure

A solution of 1-(phenylsulfonyl)-4-piperzin-1-yl-1H-indole (71 mg, 0.18 mmol) in dioxane is treated with 2-methylthio-2-imidazoline hydroiodide (52.7 mg, 0.22 mmol) and N,N-diisopropylethylamine (62 μl, 0.36 mmol), heated at 50° C. for 16 hr., cooled and concentrated in vacuo to give a residue. The residue is purified by HPLC to give the title product, 15 mg, identified by HPLC and mass spectral analyses (2.57 min; 410 M+H) using the LCMS conditions described in Table I.
