실험 절차

To a solution of 2,2,2-trichloroethyl 2-methyl-2,3-methylene-6-[2-phenyl-2-(2-chlorophenoxy)acetamido]penam-3-carboxylate (1.18 g.) in a mixture of dimethylformamide (5 ml.) and acetic acid (1.5 ml.) was added zinc powder (1.2 g.) under ice-cooling, and the mixture was stirred for 1.5 hours. After the reaction, the residue (0.65 g.) obtained by post-treating the reaction mixture in the similar manner as described in Example 1 was dissolved in methanol (2 ml.) and a solution of N,N'-dibenzylethylenediamine diacetate (0.20 g.) in water (10 ml.) was added to the solution. Crystals obtained in this manner were dissolved in methanol and subjected to reprecipitation with water to give N,N'-dibenzylethylenediamine salt of 2-methyl-2,3-methylene-6-[2-phenyl-2-(2-chlorophenoxy)acetamido]penam-3-carboxylic acid (0.55 g.), mp 107° to 110°C (dec.)
