Reaction Steps

A solution of tert-butyl 3-(2,3-dihydroxypropyl)-1-(2,6-dimethylphenyl)-5-oxopyrrolidine-3-carboxylate (1.2 g, 3.3 mmol) dissolved in THF (8 mL) was treated with NaIO4(1.4 g, 6.6 mmol) and water (2 mL). After stirring overnight at room temperature, methanol (2 mL) was added and the mixture was diluted with ethyl acetate (15 mL) and washed with water. The aqueous phase was washed with ethyl acetate and the organic layers were combined, dried and the solvent evaporated. The residue was purified by flash chromatography (SiO2, 10-100% EtOAc/hexanes) to yield tert-butyl 1-(2,6-dimethylphenyl)-5-oxo-3-(2-oxoethyl)pyrrolidine-3-carboxylate (980 mg, 88% yield). LC-MS Rt (retention time): 2.28 min, MS: (ES) m/z 332 (M+H+).
