Procedure

To a solution of 1-{[1-(2,4-dichlorophenyl)cyclopropyl]carbonyl}pyrrolidin-3-ol (3.05 g, 0.0102 mol) in acetone (50 mL, 0.7 mol) was added Jones oxidant in water (8.00 M, 2.54 mL) at 0 degrees celsius and the resulting solution was stirred at rt for 1 hour. The mixture was filtered through celite and the filtrate was concentrated. The resulting residue was dissolved in AcOEt, washed with water and brine successively, dried with MgSO4, and concentrated in-vacuo. The crude product was purified by Combiflash eluting with 40% AcOEt in hexanes.
