Procedure

To an ethyl acetate solution (465 ml) of p-methoxybenzyl 7β-formamido-3-iodomethyl-3-cephem-4-carboxylate (9.3 g) there was added dropwise over 1 hour under stirring while ice-cooling a mixed solution (176 ml) of methanol and ethyl acetate (1:4 v/v) containing 4-carbamoyl quinuclidine (2.94 g). After stirring for 30 minutes, the resulting precipitate was collected by filtration, followed by washing with ethyl acetate and then diisopropyl ether to obtain the desired product (12.0 g).
