Procedure

4-Chloromethyl-2-fluoro-1-triphenylmethylimidazole was treated with methanethiol and triethylamine in THF solution to give 2-fluoro-4-methylthiomethyl-1-triphenylmethylimidazole. This was condensed with t-butyl 3-acetoxymethyl-7-aminoceph-3-em-4-carboxylate as for the starting material of Example 42 to give t-butyl 3-acetoxymethyl-7-(4-methylthiomethylimidazol-2-yl)aminoceph-3-em-4-carboxylate, having the following n.m.r. spectrum in d6DMSO: 1.5 (s, 9H); 2.0 (s, 6H); 3.5 (d, 2H); 3.8 (d, 2H); 4.7 (d, 1H); 5.0 (d, 1H); 5.25 (d, 1H); 5.65 (d, 1H); 7.0 (s, 1H).
