Reaction Steps

To a mixture of N-[4-bromo-2-methyl-3-(trifluoromethyl)phenyl]acetamide (9.0 g) and ethanol (40 mL) was added concentrated hydrochloric acid (40 mL) at room temperature. The reaction mixture was stirred at 100° C. for 4 hours. The reaction mixture was left to be cooled to room temperature, and ethyl acetate and water were added thereto, followed by alkalification with potassium carbonate. Then, a liquid-separation operation was carried out, and the organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and then evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate 90:10-60:40) to obtain 4-bromo-2-methyl-3-(trifluoromethyl) aniline (6.9 g).
