실험 절차

A solution of 100 g of 3-buten-2-one in 100 ml of toluene stabilized with 1 g of hydroquinone was heated to 200° C. in a steel pressure vessel and held at that temperature for 4 hours. The resulting mixture was distilled under reduced pressure to give 2-acetyl-3,4-dihydro-6-methyl-2H-pyran (16A), as a liquid, b.p.: 38°-42° C., 0.02 Torr.
