実験手順

8.8 g (0.0414 mole) of cis-11-tetradecen-1-ol was combined with 4.0 g (0.0829 mole) of sodium hydroxide (50% in oil) in 200 ml of dry toluene and heated to reflux with stirring for 3 hours. 6.1 g (0.414 mole) of 5-chloro-2-furoic acid was added, followed by 25 ml of hexamethylphosphoric triamide (HMPA), and the reaction mixture refluxed with stirring for 20 hours, cooled, and acidified with acetic acid. The mixture was extracted into ether and the organic layer washed with water and with brine and evaporated to yield cis-5-(11-tetradecenyloxy)furan-2-carboxylic acid, M.P. 89°-90° C.
