To 20.4 g (0.06 mole) of 5-tetradecyloxy-2-thiophenecarboxylic acid in 500 ml of methanol is added 5.4 g (0.10 mole) of sodium methoxide. The mixture is refluxed, and the methanol is distilled off being replaced by water. The aqueous solution is cooled, the precipitate collected, and dried to give 5-tetradecyloxy-2-thiophenecarboxylic acid sodium salt.
