(0.025 mole) of 50% hydrogen peroxide and 22.7 g. (0.057 mole) of aqueous 10% sodium hydroxide at 10°-14° C. was slowly added a solution of 4-(p-tolyloxycarbonyl)-butyryl chloride in 50 ml. of ether. The resulting reaction mixture was stirred for an additional three hours. After a work-up similar to that in Example I 7.5 (theory, 10.0 g.) of liquid was obtained. The assay according to "active oxygen" content was 81.5% and the corrected yield was 61.2%. After being stored at 0° C. for several days the product solidified and had a melting point of 24°-30° C.
