Reaction Steps

The 2-naphthylmethyl 2-methyl-1-oxo-6-[2-phenyl-(4-ethyl-2,3-dioxopiperazine-1-carboxamido)acetamido]carbapen-2-em-3-carboxylate of Example 31 was taken up in a minimum of tetrahydrofuran, and added to a slurry of activated zinc (2.37 g.) in 5 ml. of acetic acid-30% tetrahydrofuran at 0° C. After 1 hour at 0° C., product was isolated according to procedures detailed in Example 2. The resulting product was taken up in ether, insolubles removed by filtration, and the filtrate evaporated to dryness in vacuo to yield 2-naphthylmethyl 2-methyl-1-oxo-6-[2-phenyl-2-(4-ethyl-2,3-dioxopiperazine-1-carboxamido)acetamido]carbapenam-3-carboxylate [36 mg., 16%; Rf 0.48 (ethyl acetate)].
