Prepared according to example 7, step 3. A solution of benzyl ((3S,4R)-2-oxo-4-((2-oxopyridin-1(2H)-yl)methyl)azetidin-3-yl)carbamate (157 mg, 0.480 mmol) in EtOH:MeOH (5:1, 4.8 mL) was evaculated and backfilled with argon (2×) followed by addition of Pd on C (10%, 33 mg). The system was evacuated and backfilled with H2 (3×). After 3 h of stirring the mixture was filtered over celite, washing with MeOH and concentrated in vacuo. The crude residue was used as such in following step.
