Reaction Steps

A mixture of pivaloyloxymethyl 6-amino-2,2-dimethylpenam-3-carboxylate toluene-p-sulphonate (200 mg.) and 2-fluorobenzimidazole (108 mg.) in methylene chloride (2 ml.) was stirred at ambient temperature for 3 hours. The reaction mixture was evaporated to dryness and the residue was triturated with ether and hexane to give pivaloyloxymethyl 6-(benzimidazol-2-yl)amino-2,2-dimethylpenam-3-carboxylate toluene-p-sulphonate (170 mg.) as a solid which had the following n.m.r. spectrum in d6DMSO: 1.14 (s, 9H); 1.43 (s, 3H); 1.60 (s, 3H); 2.24 (s, 3H); 4.55 (s, 1H); 5.5-5.9 (m, 4H); 7.0-7.54 (m, 8H).
