반응 단계
The product, containing 7β-[2-(5-tert.-butoxycarbonylaminomethyl-2-thienyl)-acetylamino]-3-(1-methyl-5-tetrazolylthiomethyl)-3-cephem-4-carboxylic acid, is dissolved in 30 ml of dioxane, 1.5 g of diphenyldiazomethane are added to the solution and the mixture is stirred for 12 hours at room temperature and then concentrated. After crystallisation from a mixture of methyl acetate and diethyl ether, the residue gives 7β-[2-(5-tert.-butoxycarbonylaminomethyl-2-thienyl)-acetylamino]-3-(1-methyl-5-tetrazolylthiomethyl)-3-cephem-4-carboxylic acid diphenylmethyl ester.
