Procedure

Benzyl 3-(1,1-dimethyl-2-oxoethyl)-3-hydroxypyrrolidine-1-carboxylate (12.70 g, 0.04359 mol) was dissolved in acetone (179.5 mL, 2.444 mol) and cooled to 15° C. and 1.0 M of hydrogen chloride in water (65.39 mL, 0.06539 mol) was added dropwise. After addition of the HCl was complete, a solution of potassium permanganate (11.0 g, 0.0697 mol) in acetone (493.6 mL, 6.722 mol) was added dropwise. The reaction mixture was stirred at room temperature for 6 h, filtered and the filter cake was washed with acetone. The filtrate was evaporated, in vacuo, diluted with methylene chloride, dried, filtered and the solvent was evaporated, in vacuo, to provide a crude product which was used directly in next step. LCMS (M+H) 308.2.
