Procedure

A suspension of 1-bromomethyl-2-fluoro-6-methoxy-5-(trifluoromethyl)naphthalene (11.16 g, 35 mmol), sodium formate (5.85 g, 86 mmol), ethanol (134 mL) and water (34 mL) was heated to reflux with stirring. Dissolution occurred within 20 minutes. After 1.5 hours the heating source was removed, 2.5N NaOH (14 mL) was added, and the reaction mixture was cooled to room temperature. The ethanol was removed, water (100 mL) was added and the solid was filtered. The white solid was washed with water and dried in vacuo to give the product in quantitative yield. A small portion was recrystallized from petroleum ether:ethyl acetate, m.p. 113°-114° C.
