Procedure

In 10 ml of N,N-dimethylformamide were stirred 0.50 g of N-acetyl-N-(2-carboxybenzyl)-2-phenoxyaniline, 0.20 g of anhydrous potassium carbonate and 0.22 ml of diethyl sulfate at room temperature for 3 hours. The reaction mixture was poured into water and extracted with ethyl acetate, and the extract was washed with 1 N hydrochloric acid, a saturated aqueous sodium bicarbonate solution and a saturated aqueous sodium chloride solution, successively, and dried over anhydrous sodium sulfate. After removal of the drying agent by filtration, the solvent was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (eluent; ethyl acetate-hexane=1:7) to give 0.50 g of N-acetyl-N-(2-ethoxycarbonylbenzyl)-2-phenoxyaniline as an oil.
