Reaction Steps

2,2,2-Trichloroethyl 2-anilinomethyl-2-methyl-6-(2-phenylacetamido)penam-3-carboxylate (1.00 g) was dissolved in dimethylformamide (5 ml). To this solution were added acetic acid (0.5 ml) and then zinc powder under cooling at -15° C. and the mixture was stirred for 6 hours. After the reaction, zinc powder was filtered off and the filtrate was poured into ethyl acetate. The solution was washed 4 times with water and dried over magnesium sulfate. After drying, the solvent was distilled off and the residue was dissolved in a small amount of methanol and then pulverized by adding water to the solution. The powder was collected by filtration, washed with water and dried to give 2-anilinomethyl-2-methyl-6-(2-phenylacetamido)-penam-3-carboxylic acid (0.50 g), mp. 120° C.
