A solution of (R)-3-tert-butyl 4-methyl 2,2-dimethyloxazolidine-3,4-dicarboxylate (5 g, 19.3 mmol) in anhydrous diethyl ether was chilled in an ice bath and 1 M LiAlH4 in diethyl ether (38 mL, 38.6 mmol) was added dropwise under an N2 atmosphere. The reaction was allowed to warm to room temperature with stirring overnight. The reaction was quenched by slowly adding saturated aqueous Na2SO4 (5 mL). The slurry was filtered through a pad of Celite. The Celite pad was rinsed with EtOAc and the solution was dried in vacuo to yield (S)-tert-butyl 4-(hydroxymethyl)-2,2-dimethyloxazolidine-3-carboxylate (2.77 g, 12 mmol) as a clear oil. [M+H] calc'd for C11H21NO4, 232. found, 232.
