To a vigorously stirred solution of 4.9 g. (0.045 mole) of 82.0% t-butyl hydroperoxide and 18.0 g. (0.045 mole) of aqueous 10% sodium hydroxide at 10°-14° C. was slowly added 8.2 g. (0.034 mole) of 4-(p-tolyloxycarbonyl)butyryl chloride (prepared from p-tolyl 4-carboxybutyrate and thionyl chloride) in 25 ml. of diethyl ether. The reaction mixture was then stirred for 3.5 hours at 8°-10° C. After a work-up similar to that in Example I 8.2 g. (theory, 10.0 g.) of white solid, m.p. 50°-55° C., was obtained. The assay according to "active oxygen" content was 93.6% and the corrected yield was 76.7%.
