Reaction Steps
1,3-Dioxolan-4-ylmethyl trifluoromethanesulfonate was prepared in the same manner as in Example 27 (a) from 1,3-dioxolan-4-ylmethanol (180 mg), pyridine (0.15 ml) and trifluoromethanesulfonic acid anhydride (537 mg). On the other hand, diphenylmethyl 7-[(Z)-2-(2 -tritylaminothiazol-4-yl)-2-methoxyiminoacetamido]-3-acetylthio-3-cephem-4-carboxylate (500 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 1,3-dioxolan-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 (494 mg; 94%).
