Procedure

4-Nitrobenzyl(1S,5R,6S)-6-((1R)-1-hydroxyethyl)-2-(7-hydroxymethyl-5-methylimidazo-[5,1-b]thiazol-2-yl)-1-methyl-1-carbapen-2-em-3-carboxylate (279 mg) was dissolved in 30 ml of dichloromethane. Manganese dioxide (500 mg) was added to the solution. The mixture was stirred at room temperature for 14 hr. The reaction solution was filtered. The filtrate was concentrated under the reduced pressure. The residue was purified by column chromatography on silica gel to give 89 mg of 4-nitrobenzyl(1S,5R,6S)-2-(7-formyl-5-methylimidazo[5,1-b]thiazol-2-yl)-6-((1R)-1-hydroxyethyl)-1-methyl-1-carbapen-2-em-3-carboxylate.
