Procedure

To a mixture of iso-butanol and 1.0 equivalent of pyridine in dry diethyl ether was added dropwise 1.3 equivalents of 2-bromopropionyl bromide at 0° C. After stirring at room temperature for 16 hours, the reaction was diluted with diethyl ether, washed with 1N HCl, water, aqueous NaHCO3, brine and dried over magnesium sulfate or sodium sulfate. Removal of the solvents at reduced pressure gave the title compound as a clear oil.
