Dess-Martin periodinane (1.08 g, 2.56 mmol) was added to an ambient temperature solution of tert-butyl 2-[4-(5-fluoropyridin-2-yl)benzyl]-2-{[(2-hydroxy-4,4-dimethylhexyl)amino]carbonyl}pyrrolidine-1-carboxylate (674 mg, 1.28 mmol) in dichloromethane (13 mL). After stirring at ambient temperature for 1 h, the reaction mixture was quenched with saturated aqueous sodium bicarbonate/saturated aqueous sodium thiosulfate (1:1) and extracted with ethyl acetate. The combined organic extracts were dried (magnesium sulfate), filtered, and concentrated in vacuo. Chromatography over silica eluting with 0-50% ethyl acetate/hexane afforded tert-butyl 2-{[(4,4-dimethyl-2-oxohexyl)amino]carbonyl}-2-[4-(5-fluoropyridin-2-yl)benzyl]pyrrolidine-1-carboxylate.
