12.88 ml. (0.092 moles) of triethylamine are added to a suspension of 9.66 g (0.046 moles) of 6-APA in 150 ml. of dichloromethane, and the mixture is stirred at room temperature until a solution is obtained. The solution is cooled to 0° C., and 25 g. (0.046 moles) of phenylmalonic acid pentachlorophenylester 5-indanylester are added to it at such a rate that the temperature of the mixture always remains below 5° C. The mixture is stirred at 0° C. for one hour, and thereafter the solvent is evaporated in vacuo. The residue is admixed with 100 ml. of ethyl acetate, whereupon 26 g. (98%) of 6-(α-[5-indanyloxy-carbonyl]-phenylacetamido)-2,2-dimethyl-penam-3-carboxylic acid triethylammonium salt separate in the form of a crystalline substance. M.p.: 153°-155° C.
