Reaction Steps
4-(4-Fluorophenoxy)-3-trifluoromethyl-aniline (1.0 g, 3.7 mmol) was dissolved in THF (5 mL), and di-t-butyl dicarbonate (965 mg, 4.43 mmol) was added thereto. The resulting mixture was stirred at 80° C. for 3 hours. The reaction solution was concentrated. The residue was dissolved in THF (5 mL), and sodium hydride (258 mg, 5.6 mmol) was added thereto. The resulting mixture was stirred at room temperature for 30 minutes, and then iodomethane (348 μL, 5.6 mmol) was added thereto. The mixture was further stirred overnight, and a saturated ammonium chloride aqueous solution was added thereto. The mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and concentrated under reduced pressure. Then, TFA (2 mL) was added to the residue, followed by stirring for 1 hour at room temperature. The reaction solution was concentrated, and a saturated sodium bicarbonate solution was added thereto. The resulting mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and concentrated under reduced pressure to give a crude product of 4-(4-fluorophenoxy)-3-trifluoromethyl-N-methylaniline.
