6-(2-phenoxyacetamido)-2,2-dimethylpenam-3-carboxylic acid (1.0 g.) was suspended in glacial acetic acid (3 cc) and sodium molybdate (0.01 g.) was added thereto. To the stirred mixture was added, dropwise, 30% hydrogen peroxide (0.7 cc) while cooling in an ice bath over a period of 5 minutes. One hour later, the precipitate was collected by filtration, washed with water and dried to yield colorless crystals (0.85 g.) of 6-(2-phenoxyacetamido)-2,2-dimethylpenam-3-carboxylic acid-1-oxide, m.p. 166.5° C.
