Reaction Steps

1-Bromo-4-fluorobutane (3.57 g, 23.1 mmol) was added dropwise to a mixture of 2-fluoro-4-hydroxybenzoic acid (3.00 g, 19.2 mmol), ethanol (11.5 ml) and water (2.3 ml), potassium hydroxide (2.37 g, 42.3 mmol) at 80° C., and the mixture was stirred at 80° C. for 17 hrs. The solvent was evaporated under reduced pressure. The residue was dissolved in water and the solution was acidified by adding 1N hydrochloric acid. The insoluble materials were filtered off and dried to give the title compound (1.73 g) as a pale-brown powder.
