PROCEDURE

实验过程

To a mixture of benzhydryl 7β-tert-butoxycarbonylamino-3-chloromethyl-3-cephem-4-carboxylate (20 g) and sodium iodide (5.82 g) in N,N-dimethylformamide (20 ml) was added 5-formamido-1-(2-formyloxyethyl) pyrazole (21.34 g) at ambient temperature. After being stirred for 24 hours at the same temperature, the mixture was poured into a mixture of water and ethyl acetate. The organic layer was separated and washed with water, aqueous sodium chloride solution, and dried over magnesium sulfate. The solution was evaporated in vacuo to give benzhydryl 7β-tert-butoxycarbonylamino-3-[3-formamido-2-(2-formyloxyethyl)-1-pyrazolio]methyl-3-cephem-4-carboxylate iodide (29.6 g).
