Acetyl chloride → 4'-Bromoacetanilide

참여 물질

반응 단계

Triethylamine (0.65 ml, 4.65 mmol) was added to a solution of 200 mg (1.16 mmol) of 4-bromoaniline in tetrahydrofuran (2 ml), and the mixture was stirred at room temperature for 5 min. Acetyl chloride (0.165 ml, 2.33 mmol) was added thereto, and the mixture was stirred at room temperature for 17 hr. The reaction was stopped by adding a saturated aqueous sodium hydrogencarbonate solution, and the reaction solution Was extracted with ethyl acetate. The organic layer was washed with water and saturated brine in that order, was dried over anhydrous sodium sulfate and was filtered. The filtrate was concentrated under the reduced pressure, and the residue was purified by column chromatography on silica gel (chloroform:methanol=20:1) to give 249 mg (yield 99%) of the title compound.
