Versuchsvorschrift

A suspension of 1-({trans-4-[6-(cyclopropylmethoxy)-1-benzofuran-2-yl]cyclohexyl}oxy)propan-2-ol (555 mg), triethylamine (0.34 mL) and methanesulfonyl chloride (0.19 mL) in THF (5 mL) was stirred at room temperature for 1 hr and extracted with ethyl acetate and water. The obtained organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The obtained residue was purified by silica gel chromatography (hexane/ethyl acetate) to give the title compound (624 mg).
