Thionyl chloride (12.8 mL, 175 mmol) was added dropwise to a stirred suspension of DL-2-methylserine hydrate, (10.4 g, 88.0 mmol) in anhydrous methanol (67 mL) at 0° C. The solids gradually dissolved during the addition. Upon complete addition the bath was removed and the mixture stirred at room temperature overnight. The solvent was then removed in vacuo to give an oil which was azeotroped twice with ether and further dried under vacuum to give the title compound.
