Procedure

A solution of 1-methoxymethoxy-naphthalene (3.76 g, 0.020 mole) in dry ether (40 mL) was treated with n-butyllithium (1.6M in hexane; 25.0 mL, 0.040 mole) at room temperature over a period of 15 minutes. After stirring for an additional 1.5 hours, a solution of cyclohexanone (4.90 g, 0.050 mole) in ether (15 mL) was added and the resulting mixture was stirred at room temperature for 2 hours. It was then quenched with saturated aqueous ammonium chloride and the crude product was isolated by extraction with ether. Chromatography with 9:1 hexane/ethyl acetate provided the title compound as a colorless oil (3.30 g, 58%).
