Dess-Martin periodinane (403 mg, 0.15 mmol) was added to an ambient temperature solution of tert-butyl[4-(4-{2-(acetylamino)-3-[(2-hydroxy-4,4-dimethylhexyl)amino]-3-oxopropyl}phenyl)-1-methyl-1H-pyrazol-3-yl]carbamate (403 mg, 0.76 mmol) in methylene chloride (10 mL). After stirring at ambient temperature for 2 h, the reaction mixture was quenched with saturated aqueous sodium thiosulfate/saturated aqueous sodium bicarbonate (1:1) and extracted with methylene chloride. The combined organic extracts were dried (magnesium sulfate) and concentrated in vacuo. Chromatography over silica eluting with 0-100% acetone/methylene chloride afforded tert-butyl [4-(4-{2-(acetylamino)-3-[(4,4-dimethyl-2-oxohexyl)amino]-3-oxopropyl}phenyl)-1-methyl-1H-pyrazol-3-yl]carbamate.
