Procedure
To a solution of tert-Butyl 2-(((Z)-(2-(((2R,3S)-2-(((2-aminoethyl)amino)methyl)-4-oxoazetidin-3-yl)amino)-1-(2-((tert-butoxycarbonyl)amino)thiazol-4-yl)-2-oxoethylidene)amino)oxy)-2-methylpropanoate (100 mg, 0.151 mmol) in chloroform (756 μl) was added CDI (98 mg, 0.604 mmol) followed by TEA (105 μl, 0.756 mmol). After stirring at rt for 1 h it was diluted with EtOAc, washed with water, brine, dried over Na2SO4 and concentrated in vacuo to afford the title compound (73 mg, 81%) as a white solid. It was used as crude in step 4. LCMS: Rt=0.70 min, m/z=596.2 (M+1) Method 2m_acidic.
