N-[3-(4-tert-Butylcyclohexan-1-yl)phenyl]-4-hydroxy-3-methoxyphenylacetamide (100 mg) obtained in Example 20, triethylamine (94 mg) and 4-dimethylaminopyridine (5 mg) are dissolved in methylene chloride (5 ml), and thereto is added dropwise acetyl chloride (40 mg) under ice-cooling. The mixture is stirred at 25° C. for 18 hours, and the reaction solution is washed with water. The organic layer is dried over sodium sulfate, and the solvent is evaporated under reduced pressure. The residue is purified by silica gel column chromatography (eluent: gradient from 0% to 100% hexane/ethyl acetate) to give the desired compound (90 mg).
