실험 절차

α-Carboxy-p-azidomethylphenylacetyl nitrophenyl polymer, prepared according to the procedure described in Canadian Pat. No. 892,580, carrying 4 m. mole of p-azidomethyl-phenylmalonic acid was suspended for 8 hours in 20 ml of dry methylene chloride solution containing 1 m. mole of 3-[(acetyloxy)methyl]-7-amino-8-oxo-5-thia-1-azabicyclo[4.2.0]-oct-2-ene-2-carboxylic acid triethylammonium salt, which is prepared from 544 mg of 7-aminocephalosporanic acid (1 m. mole) and 0.56 ml of triethylamine (1 m. mole) at room temperature. After only traces of 7-aminocephalosporanic acid remain in solution, which is determined by thin layer chromatography on cellulose in 70% aqueous propanol, the polymer was filtered off and washed with 3 portions of 5- ml each of methylene chloride. The combined filtrates were evaporated and the residue was dissolved in 20 ml of distilled water. This solution was acidified to pH 2 by adding 0.2 normal hydrochloric acid and extracted with ethyl acetate. The organic solution was dried over sodium sulfate and evaporated at room temperature. The remaining soldi was dried overnight over phosphorus pentoxide under vacuum to give 3-[ (acetyloxy)methyl]-7-[[2-[4-(azidomethyl)phenyl]-2-carboxyacetyl]amino]-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-ene-2-carboxylic acid.
