PROCEDURE
实验过程
To a solution of 4-((tert-butoxycarbonyl)amino)butanoic acid (30.7 mg, 0.15 mmol) in DCM (2 mL) at 0° C. was added DIPEA (35 μL, 0.20 mmol) and HATU (65 mg, 0.17 mmol). After 10 min, benzhydryl 1-(((Z)-(2-(((2R,3S)-2-((4-(aminomethyl)-2H-1,2,3-triazol-2-yl)methyl)-4-oxoazetidin-3-yl)amino)-1-(2-((tert-butoxycarbonyl)amino)thiazol-4-yl)-2-oxoethylidene)amino)oxy)cyclopropanecarboxylate (90 mg, 0.10 mmol) was added. After stirring at 0° C. for 1 h, the reaction mixture was diluted with DCM (40 mL), washed with 2M aq. Na2CO3 (20 mL), brine, dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified via silica gel chromatography (MeOH-DCM, 5-10%) to afford the title compound (42 mg, 46%). LCMS: Rt=1.07 min, m/z=901.5 (M+1) Method 2m_acidic.
