Tetrahydropyran-4-ylmethyl trifluoromethanesulfonate was prepared in the same manner as in Example 27 (a) from tetrahydropyran-4-yl-methanol (223 mg), pyridine (0.17 ml) and trifluoromethanesulfonic acid anhydride (596 mg). On the other hand, diphenylmethyl 7-[(Z)-2-(2-tritylaminothiazol-4 -yl) -2 -trityloxyiminoacetamido]-3-acetylthio-3-cephem-4-carboxylate (700 mg) was reacted with morpholine and triethylamine in the same manner as in Example 27(b), followed by reacting the resulting reaction product with the tetrahydropyran-4-ylmethyl trifluoromethanesulfonate in the same manner as in Example 27 (b).The reaction solution so obtained was post-treated in the same manner as in Example 27 (b) and the produced compound was recovered and purified similarly to Example 27 (b) to afford the titled compound (722 mg; 98%).
