To a solution of 5-bromo-3-(2-pyrrolidinylethyl)-1-(p-toluenesulfonyl)-indole (Example 5, 415 mg, 1 mmol) in toluene (20 mL), were added triethylsilylacetylene (0.72 mL, 4 mmol, dichlorbis(triphenylphosphine) palladium (II) (210 mg, 0.3 mmol), copper (I) iodide (57 mg, 0.3 mmol) and triethylamine (1 mL). The resulting mixture was stirred under argon at reflux overnight and then evaporated to dryness. Chromatography on silica gel (ethyl acetate followed by methanol) gave the title compound as a yellow oil (197 mg, 39%).
