3,5-Bis(1,1-dimethylethyl)benzenethiol (Example 2) (5.0 g, 0.0225 moles) was added to freshly prepared sodium ethoxide (0.0230 moles) in absolute ethyl alcohol (50 ml). After stirring for 1 hour, cyclohexene oxide (2.2 g; 0.0225 moles) was added by syringe over 5 minutes, and the reaction mixture was stirred for 60 hours at room temperature. Water (100 ml) was added, and the reaction mixture was extracted twice with 75 ml of ethyl acetate. The combined ethyl acetate extracts were washed with brine (50 ml), dried over sodium sulfate, filtered and concentrated to give the title product as a yellow solid, which was recrystallized from cold pentane. The structure assignment was supported by NMR spectroscopy. The title compound was used in Example 4.
