Reaktionsschritte

3-Methoxy-5-(trifluoromethyl)aniline (15.0 g) and 1,4-dibromobutan-2-ol (18.3 g) were stirred at 100° C. for 3 hr. After cooling to room temperature, to the reaction mixture was added saturated aqueous sodium carbonate solution, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate 90:10-50:50) to give the title compound (9.57 g, yield 47%) as an orange oil.
