Procedure

To a solution of benzyl ((2R,3S)-2-((4-(((tert-butyldimethylsilyl)oxy)methyl)-2H-1,2,3-triazol-2-yl)methyl)-4-oxoazetidin-3-yl)carbamate (500 mg, 1.12 mmol) in MeOH (15 mL) was added DOWEX-50W-X4 100-200 (1 g, 1.12 mmol) resin. After stirring at rt for 3 h, the reaction mixture was filtered, and the filtrate was concentrated in vacuo to give the title compound (assume quantitative). LCMS: Rt=0.51 min, m/z=332.1 (M+1) Method 2m_acidic.
