Reaction Steps

Benzenesulfenyl chloride (7.2 g., 0.050 mol) dissolved in benzene (15 ml.) was added to a rapidly stirred slurry of 4-hydroxy-6-methyl-2-pyrone (6.3 g., 0.050 mol) in benzene (135 ml.). There was no apparent reaction at ambient temperature, but upon heating hydrogen chloride was evolved. After heating at reflux for 2 hours, the mixture was cooled and filtered to give 11.6 g. colorless crystals, m. 160°-162.5°C., 99 percent yield.
