Versuchsvorschrift

A solution of 0.40 g (1.1 mmole) of (2R)-2,3-dihydrofuro[3,2-f][1,4]benzodioxin-2-ylmethyl 4-methylbenzenesulfonate and 1.0 g (5.0 mmole) of 3-(1,2,3,6-tetrahydro-4-pyridinyl)-1H-indole in 10 mL of DMSO was heated under nitrogen at 80° C. for 4 hours. After the reaction had cooled to room temperature, 400 mL of ethyl acetate was added and the solution was washed with 250 mL portions of saturated aqueous sodium bicarbonate, water and saturated brine, dried over sodium sulfate, filtered and concentrated in vacuum. The residue was column chromatographed on silica gel with 2% methanol in chloroform to give 0.27 g of the (S)-enantiomer of the title compound as a white solid, m.p. 208-209° C.
