(0.029 mole) of 50% H2O2 and 25.2 g. (0.063 mole) of aqueous 10% sodium hydroxide at 10°-14° C. was added slowly 10.9 g. (0.0483 mole) of 3-(p-tolyloxycarbonyl)propionyl chloride in ether solution. The resulting reaction mixture was stirred for an additional 3 hours. After a work-up similar to that in Example I 9.1 g. (theory, 10.0g.) of white solid, m.p. 94°-106° C. (decomp.) was obtained. The assay according to "active oxygen" content was 92.3% and the corrected yield was 83.9%.
