実験手順

2-(2-oxopropyl)benzoic acid (100 mg, 0.56 mmol), 4-methoxyaniline (76 mg, 0.56 mmol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (0.84 mmol) and pyridine (0.5 mL) were dissolved in chloroform (5 mL) and stirred at room temperature overnight. Chloroform was added, the organic phase was washed by aqueous citric acid solution, sodium hydrogen carbonate aqueous solution and saturated brine in that order, and dried with anhydrous sodium sulfate. The product was purified by silica gel column chromatography (hexane/ethyl acetate=10/0-3/7) to obtain the target compound (66 mg, 44%) as a light brown solid.
