Versuchsvorschrift

To a stirred solution of 3-phenyl-2-triethylsilyl-4-furanmethanol (345 mg, 1.20 mmol) and triethylamine (182 mg, 1.80 mmol) in tetrahydrofuran (15 ml) at 0 degrees under argon was added lauroyl chloride (786 mg, 3.60 mmol). This solution was allowed to warm gradually to room temperature. After stirring an additional 2 hours the white precipitate was filtered off. The filtrate was taken up into ethyl ether, washed with saturated ammonium chloride, saturated sodium bicarbonate, H2O and brine. Evaporation of the dried (magnesium sulfate) extracts gave an oil which was purified by flash chromatography on silica using 2% ethyl ether/hexanes to give the title compound.
