Procedure

To a stirred solution of 5-methyl-2-triethylsilyl-4-furanmethanol (208 mg. 0.92 mmol) and triethylamine (121 mg, 1.20 mmol) in tetrahydrofuran (10 ml) at 0 degrees under argon was added lauroyl chloride 302 mg, 1.38 mmol). This solution was allowed to warm gradually to room temperature and quenched with a 10% aqueous HCl solution. The organics were extracted into hexanes and the combined fractions were washed with a saturated aqueous solution of sodium bicarbonate, H2O and brine. Evaporation of the dried (magnesium sulfate) extracts gave an oil which was purified by filtration through silica using 2% ethyl ether/hexanes to give the title compound.
