実験手順

3-[3,5-bis(trifluoromethyl)phenyl]-3-(trifluoromethyl)pyrrolidine (0.46 g) and N-(5-bromo-2,3-dihydro-1H-inden-1-yl)propanamide (0.35 g) were dissolved in toluene and deaeration procedure was performed three times under argon atmosphere. Sodium tert-butoxide (0.25 g), Xantphos (0.05 g) and tris(dibenzylideneacetone)dipalladium (0) (chloroform adduct) (0.03 g) were added to the mixture and heated and stirred at 100° C. under argon atmosphere for 2 hours. The solution was cooled to room temperature and the reaction liquid was diluted with ethyl acetate followed by washing with water and brine. The organic layer was dried over anhydrous magnesium sulfate. The desiccant was filtered and separated, the solvent was evaporated off under reduced pressure, and the residue was purified by a silica gel chromatography to obtain N-(5-{3-[3,5-bis(trifluoromethyl)phenyl]-3-(trifluoromethyl)pyrrolidin-1-yl}-2,3-dihydro-1H-inden-1-yl)propanamide (0.51 g).
