Procedure

4-Hydroxy-6-methyl-3-(p-methylbenzylthio)-2-pyrone (10.5 g., 0.0400 mol), 30% hydrogen peroxide (5.14 g., 0.0440 mol), and 50 ml. glacial acetic acid were combined and stirred at room temperature for 20 hours. The reaction mixture was poured into 250 ml. ice-water and the recovered white precipitate was collected and dried. The solids were recrystallized from toluene to give 3.9 g. (35 percent) of the desired compound as a pale pink crystalline solid, m.p. 156°-158°C.
