실험 절차

A mixture of 3-chloropropyl 4-(3-chloropropoxy)-2-fluorobenzoate i76 (2 g, 6.47 mmol, 1 eq) and 1 M sodium hydroxide (6.47 ml, 6.47 mmol, 1 eq) in methanol (25 ml) is stirred at room temperature overnight. The mixture is concentrated under vacuum, taken up in water and extracted with diethyl ether. The aqueous phase is acidified with a 1 N hydrochloric acid solution to reach pH 2, and the resulting suspension is filtered and the solid dried to give 0.68 g of 4-(3-chloropropoxy)-2-fluorobenzoic acid i78.
