1.13 grams of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) was dissolved in 15 milliliters of dioxane, to which was then added 660 milligrams of crude 4-t-butyldimethylsiloxycyclopent-2-en-1-ol (purity 74%), after which the mixture was heated at 55° C. for 16 hours with stirring. After completion of the reaction, the precipitate separating out was filtered off. When the filtrate was concentrated under reduced pressure, 2.0 grams of a crude product was obtained.
