Versuchsvorschrift

To the solution of 1H-1,2,4-triazole (0.06 g) in DMF was added sodium hydride (0.04 g) while cooling with ice, and the mixture was warmed to room temperature and then stirred for 0.5 hr. To this solution was added the solution of 5-[3-(3,5-dichlorophenyl)-3-(trifluoromethyl)pyrrolidin-1-yl]2-fluorobenzonitrile (0.30 g) in DMF, and the mixture was heated to reflux for 6 hours. The mixture was cooled to room temperature and then poured into water, which was then extracted twice with ethyl acetate. The organic layer was combined, which was then washed with water and dried over anhydrous magnesium sulfate. After the drying agent was filtered off, the solvent was distilled away under the reduced pressure, and the residue was then purified by silica gel chromatography to yield 5-[3-(3,5-dichlorophenyl)-3-(trifluoromethyl)pyrrolidin-1-yl]-2-(1H-1,2,4-triazol-1-yl)benzonitrile (0.18 g). 1H-NMR (DMSO-d6) δ: 2.62-2.73 (1H, m), 2.95-3.03 (1H, m), 3.49-3.55 (2H, m), 3.90 (1H, d), 4.31 (1H, d), 7.09 (1H, dd), 7.29 (1H, d), 7.61 (1H, d), 7.68 (2H, d), 7.71 (1H, t), 8.26 (1H, s), 8.98 (1H, s)
