実験手順

[(2R)-8-Fluoro-2,3-dihydro-benzo[1,4]dioxin-2-ylmethyl 4-methylbenzenesulfonate (1.2 g, 3.5 mmole) was dissolved in a mixture of dimethylformamide/tetrahydrofuran (1:1 v/v, 30 mL) and 3-(1,2,3,6-tetrahydro-4-pyridinyl)-1H-indole (0.60 g, 3.0 mmole) added, followed by the addition of sodium bicarbonate (0.60 g, 7.1 mmole) and the mixture refluxed under nitrogen for 18 hours. The solvent was evaporated in vacuum, and the residue partitioned between 400 mL each of methylene chloride and water. The organic phase was dried over magnesium sulfate and filtered. The filtrate was evaporated and the residue chromatographed on silica gel using 4% methanol in chloroform as eluant. The product fractions were combined and concentrated in vacuum to give 0.20 g (16%) of the (S)-enantiomer of the title compound as a yellow solid, m.p. 174–177° C.
