Procedure

A mixture of 57.2 (0.300 mole) of 5-bromo-2-furoic acid, 121.0 g (0.45 mole) of cis-9-pentadecenol, 18.0 g (0.750 mole) of sodium hydride and 2 liters of p-xylene are heated to reflux for 48 hours. The mixture is allowed to cool, then is acidified with acetic acid and diluted with 2 liters of water. The organic layer is separated, dried, evaporated to dryness, and the residue recrystallized from hexane to give 5-(cis-9-pentadecenyloxy)-2-furoic acid.
