Versuchsvorschrift
Ethyl 2-chloro-4-(trifluoromethyl)pyrimidine-5-carboxylate (1.2 g) [see J. Med. Chem., 43, 3995 (2000)], 3-(3,4,5-trichlorophenyl)-3-(trifluoromethyl)pyrrolidine (1.5 g), and potassium carbonate (0.7 g) were added to N,N-dimethylformamide (50 mL) and the mixture was heated at 100° C. for 5 hours. After cooling, the reaction solution was poured over ice water, and then extracted with ethyl acetate. The organic layer was dried over magnesium sulfate. The solvent was evaporated off under reduced pressure, and the residue was then purified by a silica gel chromatography to obtain the title compound (2.4 g, 95%).
