Procedure

Cyclohexanol (214 mg) was added to N,N-dimethylacetamide (10 mL), and sodium hydride (60% in mineral oil, 86 mg) was added. The solution was mixed at room temperature for 15 minutes after which time 1-bromo-3-fluoro-2-(trifluoromethyl)benzene (400 mg) was added. The solution was then heated at 100° C. for 1 hour. The solution was cooled, added to water, and extracted with diethyl ether. The extract was washed with brine, dried over anhydrous sodium sulfate, and filtered. The filtrate was concentrated and purified on silica gel using 5% ethyl acetate in hexanes.
