Procedure

A solution of (2S,5R)-6-(benzyloxy)-7-oxo-1,6-diaza-bicyclo[3.2.1]octane-2-carbonitrile (XIII) (1 gm, 0.00389 mol) in a mixture of ethyl acetate and tetrahydrofuran (THF) (4:6, 4 ml:6 ml) containing 10% palladium over carbon (0.300 gm, 50% wet) was hydrogenated at 50-55 psi, for 6 hours at 25° C. The resulting mixture was filtered through a celite pad and residue was washed with mixture of ethyl acetate and tetrahydrofuran (4:6, 4 ml:6 ml). The solvent from the combined filtrate was evaporated under reduced pressure to obtain 0.649 gm of the titled compound of Formula (XIIIa) as oil, which was used as such for the next reaction without further purification.
