실험 절차

To a solution of benzhydryl 7β-tert-butoxycarbonylamino-3-(2-methyl-1-pyrazolio)methyl-3-cephem-4-carboxylate iodide (22.3 g) and anisole (22 ml) in methylene chloride (66 ml) was added trifluoroacetic acid (44 ml) under ice-cooling. After the mixture was stirred at ambient temperature for an hour, the reaction mixture was added dropwise to diisopropyl ether (600 ml). The resultant precipitates were collected by filtration to give bis(trifluoroacetic acid) salts of 7β-amino-3-(2-methyl-1-pyrazolio)methyl-3-cephem-4-carboxylate (16.83 g).
