Participants

Reaction Steps

A solution of (6S)-toluene-4-sulfonic acid 7,8-dihydro-6H-5-oxa-1-aza-phenanthren-6-ylmethyl ester (0.12 g, 0.33 mmole) and 5-fluoro-3-(1,2,3,6-tetrahydro-4-pyridinyl)-1H-indole (0.14 g, 0.65 mmole) in anhydrous DMSO (25 mL) was stirred at 80° C. for 2 hours. The reaction mixture was then poured into chloroform (100 mL) and washed with water (3×40 mL). The organic layer was dried over sodium sulfate and filtered, and the solvent was removed under vacuum. Column chromatography on silica gel (5% methanol/ethyl acetate) afforded 0.083 g (62%) of the title compound. The oxalate salt was prepared in ethyl acetate and ethanol and had mp 210° C. and [α]25D=+71.43° (c=4.68, DMSO).
