Participants

Reaction Steps

To a solution of benzyl ((2R,3S)-2-((4-(1-hydroxyethyl)-2H-1,2,3-triazol-2-yl)methyl)-4-oxoazetidin-3-yl)carbamate (460 mg, 1.33 mmol), (E)-tert-butyl (((tert-butoxycarbonyl)imino)(1H-pyrazol-1-yl)methyl)carbamate (455 mg, 1.465 mmol), and triphenylphosphine (419 mg, 1.60 mmol) in THF (7 ml) at 0° C. was added DIAD (0.311 ml, 1.598 mmol) dropwise. The reaction was stirred at room temperature overnight and concentrated to dryness. Purification of the crude residue via silica gel chromatography (EtOAc-Heptane, 30-60%) afforded the title compound (190 mg, 22%) as a light yellow solid. LCMS: Rt=0.99 min, m/z=638.4 (M+1) Method 2m_acidic.
