Procedure

To a solution of 4-hydroxy-3-isobutylthio-6-methyl-2-pyrone (8.0 g., 0.0374 mole) in glacial acetic acid (50 ml.) was added 30% hydrogen peroxide (4.3 g., 0.0374 mole). The solution was allowed to stand for several days and then was diluted with water, filtered and the cake dried, yielding 8.2 g. (95 percent) of the desired product. Recrystallization from hexane gave the pure product as an off-white solid, m.p. 102°-103°C.
