Procedure
Thionyl chloride (0.13 ml, 1.72 mmol) was added to a mixture of 5-(hydroxymethyl)-4,4-dimethyloxazolidin-2-one (50 mg, 0.34 mmol) in pyridine (1 mL) at −20° C. The mixture was allowed to stir for 15 minutes and then warmed to 60° C. for 1 hour. The mixture was concentrated under reduced pressure and the residue was purified by column chromatography on silica (20-100% ethyl acetate/hexanes) to afford 5-(chloromethyl)-4,4-dimethyloxazolidin-2-one. 1H NMR (500 MHz, CDCl3) δ 6.20 (br s, 1H), 4.38-4.35 (m, 1H), 3.75-3.70 (m, 1H), 3.62-3.57 (m, 1H), 1.42 (s, 3H), 1.31 (s, 3H).
