To a solution of benzhydryl 1-(((Z)-(2-(((2R,3S)-2-(((2-((((9H-fluoren-9-yl)methoxy)carbonyl)amino)ethyl)amino)methyl)-4-oxoazetidin-3-yl)amino)-1-(2-((tert-butoxycarbonyl)amino)thiazol-4-yl)-2-oxoethylidene)amino)oxy)cyclopropanecarboxylate (150 mg, 0.167 mmol) in DCM (1.7 mL) was added piperidine (16.50 μl, 0.167 mmol). After 2 h, the reaction mixture was concentrated in vacuo and lyophilized in CH3CN/water mixture to afford the title compound (assumed quantitative). LCMS: Rt=0.93 min, m/z=678.5 (M+1), Method 2m_acidic.
