Reaction Steps

(2.0 mmole) of 5-indanyl 2-phenylmalonate with 480 mg. (2.0 mmole) of 6-amino-2,2-dimethyl-3-(5-tetrazolyl)penam, according to the procedure of Example CXLVII affords 680 mg. (63% yield) of 6-(2-[5-indanyloxycarbonyl]-2-phenylacetamido)-2,2-dimethyl-3-(5-tetrazolyl)penam as its sodium salt. The infrared spectrum (KBr disc) of the product shows absorption bands at 1780 cm-1 (β-lactam), 1705 cm-1 (ester), 1680 cm-1 (amide I) and 1565 cm-1 (amide II). The NMR spectrum (D2O) shows absorption bands at 7.80-6.80 ppm (multiplet, aromatic hydrogens), 5.70 ppm (multiplet, C-5 and C-6 hydrogens), 5.25 ppm (doublet, C-3 hydrogen), 2.60-2.00 ppm (multiplet, C-1 and C-3 indanyl hydrogens), 2.00-1.80 ppm (multiplet, C-2 indanyl hydrogens), 1.35 ppm (doublet, C-2 methyl hydrogens) and 0.90 ppm (doublet, C-2 methyl hydrogens).
