实验步骤: o-Nitrophenyl phenyl ether was reduced catalytically to o-phenoxyaniline, m. 43°-5°, which was acetylated to 2'-phenoxyacetanilide, m. 82°-4°. Yields from both reactions were essentially quantitative. The 2'-phenoxy-acetanilide was dissolved in acetic acid and treated at 60°-80° with red fuming nitric acid to produce a 60-70% yield of 4'-nitro-2'-phenoxy-acetanilide, m. 176°-183°. This was deacetylated by refluxing with methanolic hydrochloric acid to 4-nitro-2-phenoxyaniline, m. 116°-8°. The yield was 99% of theoretical. 43°-5°, which 82°-4° Yields from both reactions

实验步骤: In 20 ml of nitrobenzene were refluxed 2.27 g of N-acetyl-2-phenoxyaniline, 1.3 ml of 2-iodoanisole, 1.38 g of potassium carbonate, 133 mg of a copper powder and 200 mg of copper bromide under heating for 8 hours. The reaction solution was cooled to room temperature, and after addition of ethyl acetate, the insoluble matter was removed by filtration. The filtrate was washed with 0.5 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=1:4) to give 660 mg of N-acetyl-N-(2-methoxyphenyl)-2-phenoxyaniline as an oil. under heating for 8 hours the insoluble matter was removed by filtration The filtrate was washed with 0.5 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 the residue was purified by silica gel column chromatography (eluent; ethyl acetate−hexane=1:4)
