実験手順

To a solution of 7β-[2-(2-aminothiazol-4-yl)-2-(Z)-(hydroxyimino)acetamido]-3-[(pyrazol-4-yl)methylthio]-3-cephem-4-carboxylic acid (300 mg) in N,N-dimethylacetamide (6 ml) was added potassium carbonate (81.8 mg) under ice-cooling. After stirring at room temperature for 30 minutes, cyclohexyl 1-iodoethyl carbonate (371.47 mg) was added thereto under ice-cooling. The mixture was stirred at the same temperature for 30 minutes, poured into a mixture of water and ethyl acetate and adjusted to pH 5 with 1N hydrochloric acid. The organic layer was separated, washed with water and brine, dried over magnesium sulfate, and evaporated to give (cyclohexyloxycarbonyloxy)ethyl 7β-[2-(2-aminothiazol-4-yl)-2-(Z)-(hydroxyimino)acetamido]-3-[(pyrazol-4-yl)methylthio]-3-cephem-4-carboxylate (15.8 mg).
