Procedure

The process described in Example 7, but using only TFA at 0°, was repeated using t-butyl 7-(1-methoxybenzimidazol-2-yl)amino-3-methylceph-3-em-4-carboxylate as starting material to give 7-(1-methoxybenzimidazol-2-yl)amino-3-methylceph-3-em-4-carboxylic acid as the hydrated trifluoroacetate salt (69%) having the following n.m.r. in d6DMSO:2.10 (s, 3H); 3.40 (d, 1H); 3.60 (d, 1H); 3.72 (s, 3H); 5.23 (d, 1H); 5.67 (d, 1H); 7.18-7.58 (m, 4H).
