Reaction Steps
0.1 mol of methyl 4-hydroxybenzoate, 0.1 mol of (S)-2-fluoro-1-octanol and 0.12 mol of triphenylphosphine are dissolved in 250 ml of tetrahydrofuran, and 0.12 mol of diethyl azodicarboxylate is added dropwise with stirring and ice cooling. The mixture is allowed to warm to room temperature, and is then stirred for a further 8 hours. The solvent is then distilled, and the methyl 4-(2-fluorooctyloxy)benzoate is purified by column chromatography. Saponification using aqueous/alcoholic potassium hydroxide solution gives (S)-4-(2-fluorooctyloxy)benzoic acid.
