Thus, the methyl ester of 6-decylamino-6-oxocaproic acid (29.9 g, 0.10 mol), hydrogen peroxide (17.0 g, 0.50 mol), and 98% methanesulfonic acid (60 mL) were reacted at room temperature for 2 hrs., the reaction mixture poured over ice, and the peroxyacid extracted into 125 mL of 60° C. ethyl acetate. The aqueous layer was discarded and the warm ethyl acetate solution was washed with two 100 mL portions of water. The ethyl acetate solution was transferred to a 250 mL Erlenmeyer flask (rinsed with 25 mL ethyl acetate), reheated to 60° C., and then cooled to -15° C. The crystals of N-decylamino-6-oxoperoxycaproic acid were collected by filtration, washed twice with 50 mL of ice-cold ethyl acetate and air dried. Yield was 21.6 g having peroxyacid AvO of 4.49% (theoretical Yield=30.1 g of 5.32% AvO), and mp 77°-85° C.
