Reaction Steps

To a stirred solution of 5-[3-(trifluoromethoxy)phenoxy]-2-[4-(trifluoromethyl)phenyl]-2H-1,2,3-triazole-4-methanol (i.e. the product of Example 5, Step I, 0.075 g, 0.18 mmol) in anhydrous tetrahydrofuran (2 mL) was added sodium hydride (0.011 g, 0.28 mmol, 60% dispersion in oil). After 15 min., iodomethane (0.017 mL, 0.27 mmol) was added. The mixture was stirred at 23° C. for 1.75 h. The reaction mixture was diluted with water (20 mL), extracted with diethyl ether (3×15 mL), and washed with saturated aqueous sodium chloride solution (10 mL). The organic layer was dried (MgSO4) and concentrated under reduced pressure to afford the crude product which was purified by chromatography on silica gel eluting with 0 to 10% ethyl acetate in hexanes to obtain the title compound (0.045 g.) as a clear, colorless oil.
