Reaction Steps

To 1.70 g of 2-cyclohexylcarbonyl-4-tert-butylanisole [prepared in Reference Example 2 (a)] dissolved in 10 ml of glacial acetic acid were added 1.0 ml of 57% hydroiodic acid and 2.0 ml of 47% hydrobromic acid, and heated at reflux for 2 hours. The reaction mixture was poured into 50 ml of ice-water, extracted with diethyl ether, and the extract was washed with saturated aqueous sodium thiosulfate solution, water and saturated brine successively, dried over magnesium sulfate anhydride and concentrated at reduced pressure. The residue was chromatographed on silica gel column using a mixed solvent of methylene chloride and cyclohexane (1:2) as an eluting agent to give 1.54 g of the title compound having the following physical properties.
