Reaction Steps
15.6 Grams (0.1 mol) of 4-hydroxy-2-fluorobenzoic acid was dissolved in 140 ml of dichloromethane. To the mixture were consecutively added 16 ml of triethylamine, 0.1 g (0.11 mol) of n-decanoic acid chloride and 0.97 (0.0079 mol) of dimethylaminopyridine, and the mixture was stirred at room temperature for a whole day. 10% Hydrochloric acid in an amount of 50 ml was added, and the mixture was subjected to extraction with 100 ml of ether three times. The organic layer was washed with a sodium chloride aqueous solution three times and dried over anhydrous sodium sulfate. The solvent was distilled off, the residue was washed with 400 ml of hexane to give 25.5 g of the intended product.
