2-Chlorocyclohexanone (0.6 g, 0.0045 moles) was added to a cold (+5° C.) solution of 3,5-bis (1,1-dimethylethyl)benzenethiol (Example 2)(1.0 g, 0.0045 moles) in tetrahydrofuran (50 ml). The solution was stirred for 15 minutes. Triethylamine (1.25 ml) was added, the cold bath was removed and the mixture was stirred at room temperature for 20 hours and then at 50° C. for 2 hours. The mixture was cooled to room temperature and filtered to remove a white solid. The filtrate was concentrated to an oil. The product was purified by silica gel chromatography to give a white solid which was recrystallized from hexane (DSC 81.49° C.). The structure was supported by NMR and Ir.
