Procedure

A mixture of diphenylmethyl 7-[(Z)-2-(2-tritylaminothiazol-4-yl)-2-methoxyiminoacetamido]-3-iodomethyl-3-cephem-4-carboxylate (VII-1, 7.8 g, 8.4 mmoles) and triphenylphosphine (4.4 g, 16.8 mmoles) in benzene (160 ml) was stirred at room temperature for 1 hour. The resulting precipitate was collected by filtration to afford 8.0 g of the title compound VIII-1. The mother liquor was concentrated and the residue was triturated with n-hexane to yield an additional amount (1.3 g) of VIII-1. Total yield 9.3 g (93%).
