Reaction Steps

A mixture of 30.0 g (0.157 mole) of 5-bromofuroic acid, 64.0 g (0.236 mole) of octadecanol and 500 ml of bis(2-methoxyethyl)ether is stirred at room temperature under nitrogen after which 9.45 g (0.393 mole) of sodium hydride is added. The mixture is refluxed about 22 hours, allowed to cool and poured into an ice-water mixture, acidified with acetic acid and extracted with ether. The ether layer is washed with water and salt water, dried over sodium sulfate, and filtered. The solvent is evaporated off replacing the ether with hexane. Upon cooling to room temperature a solid forms which is recrystallized from methanol to give 5-octadecyloxy-2-furoic acid, M.P. 117°-118° C.
