실험 절차

To a reaction vessel, N-[(1S)-1-(4-bromophenyl)ethyl]cyclopropanecarboxamide (134 mg), 3-[3,5-bis(trifluoromethyl)phenyl]-3-(trifluoromethyl)pyrrolidine (211 mg), sodium t-butoxide (96 mg), tris(dibenzylideneacetone)dipalladium(0)-chloroform adduct (10 mg), 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (18 mg) and toluene (6 ml) were added, and reacted in a microwave reactor (Initiator™, manufactured by Biotage) for 10 minutes at 120° C. Upon the completion of the reaction, ethyl acetate was added and the precipitates were filtered by using silica gel. The solvent was distilled off under reduced pressure and the residue was purified by silica gel column chromatography to obtain N-[(1S)-1-(4-{3-[3,5-bis-(trifluoromethyl)phenyl]-3-(trifluoromethyl)pyrrolidin-1-yl}phenyl)ethyl]cyclopropanecarboxamide (269 mg). 1H-NMR (CDCl3) as given in Table 2
