실험 절차

Thionyl chloride (4.89 g) was added to [4-(trifluoromethyl)thiophen-2-yl]methanol (500 mg) at room temperature, and the mixture was stirred for 3 hr. The reaction mixture was concentrated, and the obtained residue was purified by silica gel column chromatography (hexane/ethyl acetate) to give the title compound (275 mg).
