反応手順

To a solution of 2.76 g (20 mmol) of 4-hydroxybenzoic acid and 800 mg (200 mmol) of sodium hydroxide in 12 ml of water was added 250 mg of methyl tricaprylammonium chloride and 4.67 g (17 mmol) of n-tetradecylbromide. The mixture was heated at reflux for 4 h and then diluted with 30 ml of water. The mixture was extracted with 2×30 ml ether. The ether extracts were combined and washed with water and saturated NaCl solution. The solvent was removed in-vacuo and the residue purified by flash chromatography (silica; 10% ethyl acetate in hexanes) to give the title compound as a white solid.
