PROCEDURE

实验过程

A solution of 7-[2-(2-formamidothiazol-4-yl)-2-tert-butoxycarbonylmethoxyiminoacetamido]-3-[1-(2-tert-butoxycarbonylaminoethyl)-1H-tetrazol-5-yl]thiomethyl-3-cephem-4-carboxylic acid (syn isomer, 3.5 g.) and conc. hydrochloric acid (1.9 g.) in methanol (35 ml.) was stirred at room temperature for 1.5 hours. After concentration, the residue was pulverized with diethyl ether to give 7-[2-(2-aminothiazol-4-yl)-2-tert-butoxycarbonylmethoxyiminoacetamido]-3-[1-(2-tert-butoxycarbonylaminoethyl)-1H-tetrazol-5-yl]thiomethyl-3-cephem-4-carboxylic acid hydrochloride (syn isomer, 3.32 g.).
