Procedure

4-Hydroxyquinaldic acid, ethyl ester (16 g), allyl bromide (22.5 g) and anhydrous potassium carbonate (30 g) in dimethylformamide (300 ml) were stirred and heated on a steam bath for 20 hours. The mixture was filtered, the filtrate was evaporated and the residue was crystallised from a mixture of ethyl acetate and light petroleum (b.p. 60°-80°) to give 4-allyloxyquinaldic acid, ethyl ester.
