Procedure

200 mg of (1R, 5S, 6S)-2-[(2S, 4S)-2-(4-acetimidoylpiperazin-1-ylcarbonyl)pyrrolidin-4-ylthio]-6-[(1R)-1-hydroxyethyl]-1-methyl-1-carbapen-2-em-3-carboxylic acid [prepared as described in step (b) above] were dissolved in 5 ml of water, after which 0.43 ml of 1N aqueous hydrochloric acid was added. The resulting mixture was worked up and purified by reverse phase column chromatography through 30 ml of Cosmo Sil 75C18 -PREP (a trade mark for a product of Nacalai Tesque), using water as the eluent. Those fractions containing the title compound were combined and lyophilized to give 149 mg of the title compound as a powder.
