A mixture of [(2R)-8-methoxy-2,3-dihydro-1,4-benzodioxin-2-yl]methyl 4-methylbenzene-sulfonate (0.5 g, 1.42 mmole) and cis-3-(5-fluoro-1H-indol-3-yl)-cyclopentyl-amine (0.24 g, 1.1 mmol) in anhydrous DMSO (10 mL) was heated at 80° C. for 30 h. The cooled reaction mixture was poured into 1 N aqueous NaOH (50 mL) and extracted with ethyl acetate (3×50 mL). The combined organic layers were washed with water (50 mL) and brine (50 mL), then were dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo to give 0.5 g of crude product. Flash chromatography on silica gel (10% MeOH/ethyl acetate) afforded 0.2 g (48%) of the title compound as a thick oil, which was converted to its hydrochloride salt (0.195 g): MS (ESI) m/z 397 [M+H]+.
