PROCEDURE

实验过程

A mixture of diphenylmethyl 7-[(Z)-2-(1-t-butoxycarbonylcyclobut-1-oxyimino)-2-(2-tritylaminothiazol-4-yl)acetamido]-3-iodomethyl-3-cephem-4-carboxylate (VII-5', 6.4 g, 6 mmoles) and triphenylphosphine (2.4 g, 9 mmoles) in benzene (120 ml) was stirred at room temperature for 2 hours and diluted with n-hexane (ca. 500 ml). The resulting precipitate was collected by filtration to afford 7.5 g (94%) of the title compound VIII-B 5'.
