Reaction Steps

IBX (293 mg, 0.472 mmol) was added to a solution of (2R)-1-benzyl-N-(3-hydroxy-4-(methoxyamino)-4-oxo-1-phenylbutan-2-yl)-5-oxopyrrolidine-2-carboxamide (143 mg, 0.337 mmol) in DMSO (5 mL). After stirring for 2 h more IBX (105 mg, 0.169 mmol) was added and the stirring continued overnight. The saturated aqueous NaHCO3 solution was added and the reaction mixture was diluted with water and DCM. The organic layer was separated and the aqueous layer was extracted with DCM. The combined organic layers were washed with water and dried (MgSO4). The crude product obtained was dissolved in a minimal amount of DCM and diethylether was added. The precipitate formed was isolated and dried in vacuo. The title compound was obtained as a colourless solid (12 mg, 8%)
