Procedure

10% Palladium/charcoal catalyst (15 mg), suspended in 50% aqueous dioxan (4 ml) was pre-hydrogenolysed for 20 mins. To this was then added a solution of p-nitrobenzyl 3-[E-2-carbamoylethenyl thio]-6-[1-p-nitrobenzyloxycarbonyloxyethyl]-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate (11 mg) in 50% aqueous dioxan (6 ml). After hydrogenolysis for 21/2 hr., sodium hydrogen carbonate (1.5 mg) in water (1 ml) was added. The dioxan was removed in vacuo and the aqueous phase extracted with ethyl acetate. The aqueous solution was shown to contain 3.75 mgs; (65%), of sodium 3-[E-2-carbamoylethenylthio]-6-[1-hydroxyethyl]-7-oxo-1-azabicyclo[3.2.0]hept-2-ene-2-carboxylate, νmax. (H2O) 316 nm.
