Procedure
14.0 g (0.132 mol) of Na2CO3, dissolved in 150 ml of water, are added to a suspension of 78.0 g (0.088 mol) of benzhydryl 7-phenylacetamido-3-(triphenylphosphonio)methyl-3-cephem-4-carboxylate iodide (Example 7) in 400 ml of methylene chloride and the mixture is stirred vigorously at room temperature for 15 minutes. The CH2Cl2 layer is separated off, the aqueous phase is extracted again with 200 ml of CH2Cl2 and the combined organic phases are dried over sodium sulphate. The methylene chloride phase is concentrated to dryness and the residue is stirred in about 600 ml of acetone for 1 hour. The product is filtered off with suction and rinsed thoroughly with acetone.
