Procedure

N-Propyl iodide (4.9 mL, 50 mmol) was added to a stirring suspension of 6-hydroxy-1,2,3,4-tetrahydronaphthalene (Intermediate 1, 2.07 g, 10 mmol), potassium carbonate (6.9 g, 50 mmol), in acetone (50 mL), and the mixture was stirred at reflux for 14 h. The solution was poured into a separatory funnel, water was added, and the products were extracted three times with hexane. The combined organic layers were washed with brine and dried over magnesium sulfate. The solvent was removed in vacuo to give the title compound as a yellow oil.
