Reaction Steps

To a solution of benzyl ((2R,3S)-2-((4-(aminomethyl)-2H-1,2,3-triazol-2-yl)methyl)-4-oxoazetidin-3-yl)carbamate 2,2,2-trifluoroacetate (340 mg, 0.77 mmol) in dioxane (6 mL) was added DIPEA (0.147 mL, 0.842 mmol) and a solution of tert-butyl 3-((N,N′-bis(tert-butoxycarbonyl)-1H-pyrazole-1-carboximidamido)methyl)azetidine-1-carboxylate (367 mg, 0.765 mmol) in dioxane (1 mL). After heating to 60° C. for 12 h, the reaction mixture was concentrated in vacuo and purified via silica gel chromatography (EtOAc-heptane, 0-95%) to afford the title compound (390 mg, 69%). LCMS: Rt=0.94 min, m/z=742.5 (M+1) Method 2m_acidic.
