Participants

Reaction Steps

p-Methoxybenzyl 7β-[(Z)-2-(5-amino-1,2,4-thiadiazol-3-yl)-2-methoxyiminoacetamido]-3-iodomethyl-3-cephem-4-carboxylate (700 mg) was dissolved in a mixed solution of ethyl acetate (50 ml) and methanol (1 ml). After the whole was ice-cooled, a solution of ethyl acetate (2.8 ml) of 4-methyl-quinuclidine (114 mg) was added thereto, and the mixture was stirred for 15 minutes. The resulting precipitate was recovered by filtration, followed by wasing with ethyl acetate to obtain p-methoxybenzyl 7β-[(Z)-2-(5-amino-1,2,4-thiadiazol-3-yl)-2-methoxyiminoacetamido]-3-(4-methyl-1-quinuclidinio)methyl-3-cephem-4-carboxylate iodide (770 mg).
