1 mol of 2,5-dihydroxybenzoic acid and 0.5 mol of cesium carbonate were added to 200 ml of acetone and 200 ml of water and dissolved therein by stirring. After completely dissolving, the resultant solution was concentrated to dryness to give 1 mol of cesium 2,5-dihydroxybenzoate. 85.8 g (0.3 mol) of cesium 2,5-dihydroxybenzoate, 57.9 g (0.3 mol) of bromooctane and 300 ml of DMF were introduced into a reactor and reacted under a nitrogen gas stream at 100° C. for 3 hours. The reaction solution was concentrated, washed with water and dried to give 78 g (0.29 mol) of 2,5-dihydroxybenzenecarboxylic octane.
