Reaction Steps

To a 25 mL round bottom flask were added ethyl 8-methoxy-4-hydroxynaphthalene-2-carboxylate (0.25 g, 1.02 mmol), Cs2CO3 (0.33 g, 1.02 mmol), iodoethane (0.79 g, 5.1 mmol) and DMF (4 mL). The resulting reaction mixture was stirred at 70° C. overnight. After cooling to room temperature, the reaction was diluted with EtOAc (30 mL), washed with water and brine. The organic layer was dried over Na2SO4, filtered and concentrated. The crude product was purified on a silica gel column eluting with a gradient of 10-20% EtOAc/hexanes to give the title intermediate (0.19 g) as a light yellow solid.
