Versuchsvorschrift

To a solution of 4.70 g of 4-nitrobenzyl (1S,5R,6S)-6-((1R)-1-hydroxyethyl)-2-(imidazo[5,1-b]thiazol-3-yl)-1-methyl-1-carbapen-2-em-3-carboxylate in 10 ml of THF and 10 ml of {fraction (1/15)} M phosphate buffer was added 240 mg of 10% Pd-C. The reactor was purged with hydrogen, and the reaction mixture was stirred at room temperature for 3 hours. The catalyst was collected by filtration and washed with water. The filtrate was washed with ethyl acetate, and the aqueous layer was purified by column chromatography on DIAION HP-20 to give 27.5 mg of the title compound.
