Participants

Reaction Steps

A solution of (6R)-toluene-4-sulfonic acid 7,8-dihydro-6H-5-oxa-1-aza-phenanthren-6-ylmethyl ester (0.17 g, 0.47 mmole) and 5-fluoro-3-(1,2,3,6-tetrahydro-4-pyridinyl)-1H-indole (0.20 g, 0.94 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 0.11 g (55%) of the title compound. The fumarate salt was prepared in ethyl acetate and isopropyl alcohol and had mp 210° C. and [α]25D=−60.030° (c=4.5, DMSO).
