Procedure:
To 28.0 g of 2-methoxy-6-(trans-4-propylcyclohexyl)naphthalene were added 280 ml of acetic acid and 280 ml of 48% hydxobromic acid. The reaction mixture was then heated under reflux for 12 hours. The reaction solution was then allowed to cool to room temperature. To the reaction solution was then added 500 ml of water to cause crystallization. The crystal thus precipitated was then filtered off. The crystal was washed with water, and then dried under reduced pressure to obtain 26.8 g of 6-(trans-4-propylcyclohexyl)-2-naphthol.

After being stirred for 12 hours at 80° C., the solution was poured into a mixture of ethyl acetate and water. The organic layer was washed with 1N--HCl solution, sat. NaHCO3, and brine, dried over MgSO4, and evaporated in vacuo. The residue was dissolved into a mixture of toluene (100 ml) and 1,8-diazabicyclo[5.4.0]-7-undecene (17 ml) and the mixture was stirred for 3 days at 100° C. The solution was washed with 1N--HCl solution, sat. NaHCO3, and brine, dried over MgSO4, and evaporated in vacuo. The residue was purified by chromatography on silica gel to afford 5-t-butyldiphenylsilyloxy-1-ethoxycarbonylmethyl-3,4-dihydronaphthalene (20.3 g).
