Procedure

To a solution of 2-(((Z)-(2-(((2R,3S)-2-((4-(aminomethyl)-2H-1,2,3-triazol-2-yl)methyl)-4-oxo-1-sulfoazetidin-3-yl)amino)-1-(2-aminothiazol-4-yl)-2-oxoethylidene)amino)oxy)-2-methylpropanoic acid (60 mg, 0.089 mmol) and pyrazole-1-carboxamide hydrochloride (16 mg, 0.11 mmol) in DMF (3 mL) was added DIPEA (45 μL, 0.27 mmol). After stirring for 16 h, the solution was concentrated and washed with ether. The crude residue was purified by reverse phase prep HPLC (XBridge, 30×150 mm, 5 μm, C18 column; ACN-water with 0.1% formic acid modifier, 1 mL/min), affording the title compound (7.5 mg, 15%) as a white solid. LCMS: m/z=571.9 (M−1); 1H NMR (400 MHz, D2O): δ 7.55 (s, 1H), 6.78 (s, 1H), 5.38 (d, J=5.2 Hz, 1H), 4.82-4.76 (m, 1H assumed; obscured by solvent residual peak), 4.76-4.72 (m, 2H assumed; obscured by solvent residual peak), 4.32 (s, 2H), 1.15 (s, 3H), 1.14 (s, 3H).
