Procedure
p-Methoxybenzyl 7β-phenylacetamido-3-chloromethyl-3-cephem-4-carboxylate (980 mg) was suspended in acetone (20 ml), and sodium iodide (362 mg) was added to the suspension and stirred at room temperature for 1 hour. To the resulting suspension was added 4-carbamoylquinuclidine (313 mg) under ice-cooled condition, and the mixture was stirred for 2 hours. The reaction mixture was filtered, and diethyl ether (70 ml) was added to the filtrate. The deposited solid was filtered to obtain the desired product (500 mg).
