Versuchsvorschrift

A 5 N aqueous hydrochloric acid solution (1 ml) was added to a solution of 72.4 mg of (3S,4R)-3-[(1R)-1-(t-butyldimethylsilyloxy)ethyl]-4-{(1R)-1-methyl-2-[7-(pyridin-3-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-2-oxoethyl}-1-[4-nitrobenzyloxycarbonyl(triphenylphosphoranylidene)-methyl]azetidin-2-one in 2 ml of methanol, and the mixture was stirred at room temperature for 2 hr. The reaction mixture was neutralized with saturated aqueous sodium bicarbonate solution and was extracted with ethyl acetate. The organic layer was washed with saturated brine and was dried over anhydrous magnesium sulfate. The solvent was removed by evaporation, and the residue was purified by thin layer chromatography (developed with 10% methanol/methylene chloride) to give 46.9 mg of (3S,4R)-3-[(1R)-1-hydroxyethyl]-4-{(1R)-1-methyl-2-[7-(pyridin-3-yl)carbonylimidazo[5,1-b]thiazol-2-yl]-2-oxo ethyl}-1-[4-nitrobenzyloxycarbonyl(triphenyl phosphoranylidene)methyl]azetidin-2-one.
