Participants

Reaction Steps

To a suspension cooled to 0° C. of sodium hydride (126 mg, 60 wt. % oil dispersion) in N,N-dimethylformamide (5 ml) was added dropwise, 1,1,1-trifluoro-2-methylpropan-2-ol (320 μL) under argon atmosphere, and the mixture was stirred for 15 minutes. To this reaction mixture was added dropwise 1-bromomethyl-3-chlorobenzene (320 μL), and the mixture was stirred for 3 hours. To this reaction mixture was added water, and the mixture was extracted with ethyl acetate. This organic layer was washed with water and a saturated aqueous solution of sodium chloride, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (eluent: n-hexane/ethyl acetate=1/0 to 40/1) to give the titled compound (389 mg).
