Procedure
Prepared in an analogous manner to example 4, step 3 using benzyl ((2R,3S)-2-((5-methyl-1H-tetrazol-1-yl)methyl)-4-oxoazetidin-3-yl)carbamate (97 mg, 0.31 mmol) and Pd on C (10%, 50 mg) in EtOH:MeOH (5:1, 3.0 mL) for 3 h. The crude residue was used as such in following step. LCMS: Rt=0.11 min, m/z=183.2 (M+1) Method 2m_acidic.
