実験手順

A mixture of 0.50 g (1.2 mmole) of [(8R)-2-trifluoromethyl-7,8-dihydro-3H-6,9-dioxa-1,3-diaza-cyclopenta[a]naphthalen-8-yl]methyl 4-methylbenzenesulfonate and 1.0 g (5.0 mmole) of 3-(1,2,3,6-tetrahydro-4-pyridinyl)-1H-indole in 8.0 mL of DMSO was heated at 85° C. under nitrogen for 6 hours. The reaction was allowed to come to room temperature, diluted to 400 mL with ethyl acetate, washed with 400 mL portions of saturated aqueous sodium bicarbonate, water and saturated brine, dried over sodium sulfate, filtered and evaporated in vacuum. The residue was column chromatographed on silica gel with 1% methanol in chloroform as eluant and the product fractions concentrated in vacuum to give 0.40 g of the desired compound as the free base. Recrystallization from ethanol with the addition of 0.12 g of fumaric acid gave 0.24 g of the (S)-enantiomer of the title compound as a pale yellow solid fumarate, m.p. 231-233° C.
