Sodium carbonate (1.27 g) was added to a solution of 1.09 g of 2-aminophenol in a mixed solvent composed of 20 ml of ethyl acetate and 20 ml of water. To the resulting mixture was added a solution of 3.01 g of oleoyl chloride in 10 ml of ethyl acetate portion-wise with stirring under ice cooling. The stirring was continued for additional 2 hours. After completion of the reaction, the organic layer was separated, washed with water and then with saturated saline, and dried over anhydrous sodium sulfate. After removal of the solvent by evaporation, the residue obtained was purified by silica gel column chromatography to obtain 3.40 g of the objective compound (yield: 91%).
