Procedure

To a stirred solution of 1.91 g of 4-fluoro-1-hydroxynaphthalene in 40 ml of dry dichloromethane in an ice/salt bath was added by syringe 2.64 ml of diisopropylethylamine followed by 1.11 ml of methoxymethylchloride. The mixture was stirred at 0° C. for 0.5 h, allowed to warm to ambient temperature and stirred for 14 h. The reaction mixture was poured into saturated sodium bicarbonate, extracted with dichloromethane, dried (sodium sulphate), filtered and concentrated to a yellow oil. The material was purified by flash chromatography on silica gel eluting with toluene/heptanes to provide 1.98 g of 4-fluoro-1-methoxymethoxynaphthalene.
