Reaction Conditions

Reaction Steps

To a solution of ethyl {6-[(3-phenoxybenzyl)oxy]-3,4-dihydronaphthalen-1-yl}acetate (0.622 g, 1.50 mmol) in a mixed solvent of ethanol (3 mL) and tetrahydrofuran (3 mL) was added 2 M aqueous sodium hydroxide solution (3 mL), and the mixture was stirred at room temperature for 1 hr and further at 70° C. for 5 hr. Water was added to the reaction mixture, and the mixture was acidified with 1 M hydrochloric acid and extracted with ethyl acetate. The extract was washed with saturated brine, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (20%-80% ethyl acetate/hexane) and recrystallized from ethyl acetate-hexane to give the title compound (0.198 g, yield 34%) as colorless needle crystals.
