Thionyl Chloride → 3-[Chloro(cyclohexyl)methyl]-6-methoxy-2-methyl-1-benzofuran

Participants

Reaction Steps

To a solution (10 mL) of cyclohexyl(6-methoxy-2-methyl-1-benzofuran-3-yl)methanol (499 mg) synthesized above in toluene was added thionyl chloride (159 μL), and the mixture was stirred at room temperature for 1 hr. The reaction mixture was poured into ice-cooled saturated aqueous sodium hydrogen carbonate solution, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure to give the title object compound (530 mg, 99%) as a pale-yellow oil.
