To a solution of benzhydryl 1-(((Z)-(1-(2-((tert-butoxycarbonyl)amino)thiazol-4-yl)-2-(((2R,3S)-2-((4-(hydroxymethyl)-2H-1,2,3-triazol-2-yl)methyl)-4-oxoazetidin-3-yl)amino)-2-oxoethylidene)amino)oxy)cyclopropanecarboxylate (440 mg, 0.614 mmol) in THF (4 mL) was added MnO2 (1.2 g, 13.51 mmol). After stirring at rt for 20 h, the reaction mixture was filtered through a pad of celite with THF wash (20 mL). The filtrate was concentrated, and the residue was purified via silica gel chromatography (MeOH-DCM, 0-5%) to afford the title compound (300 mg, 68%). LCMS: Rt=1.04 min, m/z=715.3 (M+H). Method 2m_acidic.
