PROCEDURE

实验过程

A mixture of p-nitrobenzyl 6-amino-2,2-dimethylpenam-3-carboxylate toluene-p-sulphonate (523 mg.) and 2-fluoroimidazole (100 mg.) in acetonitrile (2 ml.) was stirred at 50° for 3 hours. The resulting solution was evaporated to dryness and the residue obtained was triturated with ether to give p-nitrobenzyl 2,2-dimethyl-6-(imidazol-2-yl)aminopenam-3-carboxylate toluene-p-sulphonate as a 50% pure solid (572 mg.) which was used without further purification.
