3(6-Bromo-2-methyl-1H-indol-3-ylsulfanyl)-benzoic acid methyl ester (1.13 g, 3.0 mmol) was dissolved in DMF and cooled to 0° C. then sodium hydride (60% dispersion in mineral oil, 0.156 g, 3.9 mmol) was added. After 5 minutes benzyl bromide (0.500 mL, 4.2 mmol) was added and the reaction was allowed to warm to room temperature. After 1 hour the reaction was re-cooled to 0° C. then quenched with aqueous HCl (5 mL, 1N). After extraction the crude product was purified by silica gel chromatography (0-30% EtOAc in hexanes) to afford the title compound.
