Acetic Acid → HCID 54737320, compound

Participants

Reaction Steps

3-Benzylthio-4-hydroxy-6-methyl-2-pyrone (7.45 g., 0.0282 mol) and 30% hydrogen peroxide (3.7 g., 0.033 mol) were combined in 30 ml. glacial acetic acid and stirred at room temperature for 20 hours. The solution was then diluted with a mixture of toluene and ethanol (5:1) and warmed in vacuo to codistil the acetic acid. The recovered tan solid was recrystallized from toluene (DARCO) to give 5.4 g. (69 percent) of the desired product: m.p. 150°-153°C. One additional recrystallization from toluene gave the pure compound: m.p. 155°-156°C.
