Formic Acid → (3S,4R)-4-((1H-1,2,4-triazol-1-yl)methyl)-3-aminoazetidin-2-one

Participants

Reaction Steps

To a solution of benzyl ((2R,3S)-2-((1H-1,2,4-triazol-1-yl)methyl)-4-oxoazetidin-3-yl)carbamate (38 mg, 0.126 mmol) in MeOH (5 mL) was added Pd black (6.7 mg, 0.063 mmol) followed by formic acid (339 μL, 8.83 mmol). After 1 h of stirring, the mixture was filtered over celite, washing with MeOH, and the filtrate was concentrated in vacuo. The solution was lyophilized and the crude material was used directly in the subsequent step. LCMS: Rt=0.14 min, m/z=168.1 (M+1) Method 2m_acidic.
