Ethyl 2-chloro-6-(trifluoromethyl)pyridin-5-carboxylate (0.95 g), 3-[3,5-bis-(trifluoromethyl)phenyl]-3-(trifluoromethyl)pyrrolidine (1.4 g) and potassium carbonate (0.7 g) were added to N,N-dimethylformamide (30 ml), and heated for 5 hours at 100° C. After cooling, the reaction mixture was poured in ice water and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, the solvent was distilled off under reduced pressure, and purified by silica gel column chromatography to obtain ethyl 6-{3-[3,5-bis-(trifluoromethyl)phenyl]-3-(trifluoromethyl)pyrrolidin-1-yl}-2-(trifluoromethyl)nicotinate (1.7 g).
