Procedure

To a clear solution of trans-3-{N′-(6-carboxymethoxy-7-oxo-1,6-diaza-bicyclo[3.2.1]octane-2-carbonyl)-hydrazinocarbonyl}-(R)-piperidin-1-carboxylic acid tert-butyl ester (150 mg, 0.32 mmol) in dichloromethane (2 ml) was added trifluoroacetic acid under stirring at −10° C. The reaction mixture was stirred for about 1 hour at −10° C. and the solvents were evaporated under vacuum to provide a residue. The residue was triturated successively with diethyl ether (25 ml) and acetonitrile (25 ml) and solvents were decanted to provide solid that was dried under vacuum to provide 59 mg of titled compound in 50% yield.
