(S)-4-Formyl-2,2-dimethyloxazolidine-3-carboxylic acid tert-butyl ester Add dropwise over 2 hours a solution of pyridine sulfur trioxide (390 g, 2452.83 mmol) in dimethylsulfoxide (1600 mL) to a 6 C. maintained solution of <strong>[108149-63-9](S)-4-hydroxymethyl-2,2-dimethyloxazolidine-3-carboxylic acid tert-butyl ester</strong> (350 g, 1515.15 mmol) in diisopropylethylamine (1225 mL) with a dimethylsulfide trap. Over 30 minutes add water (1050 mL) keeping temperature below 15 C. Stir at 15 C. for 1.5 hours under a stream of nitrogen. Extract with ethyl acetate (5 L), wash with 5%-aqueous citric acid (2*1.5 L), saturated aqueous sodium chloride (2*1.5 L), dry (magnesium sulfate), filter, and concentrate to give the desired compound which is used in the next reaction without further purification (365 g).
