Procedure

To a 250 milliliter three-necked flask were added 0.15 mole of 2-(hydroxymethyl)tetrahydrofuran, 0.15 mole of triethylamine, and 100 milliliters of diethylether. The flask was immersed in ice, and 0.15 mole of 2-bromopropanoyl chloride introduced dropwise. The ice bath was removed, and the reaction stirred at ambient temperature for two hours. The mixture was extracted with an equal volume of water, and the organic phase dried over sodium sulfate. Pecanration and solvent removal resulted in 2-tetrahydrofuranylmethyl 2-bromopropanoate in 94% yield.
