Reaction Steps
The 2-(4-trifluoromethoxyanilino)ethanol may be prepared in the following manner: 88.5 g of 4-trifluoromethoxyaniline and 31.2 g of 2-bromoethanol are heated at 160° C. for 1.5 hours. After cooling to a temperature in the region of 20° C., the reaction medium is taken up in 200 cm3 of dichloromethane and the insoluble matter is filtered and the filtrate concentrated to dryness under reduced pressure. After purification by chromatography on a silica column, using an ethyl acetate-cyclohexane mixture (40-60 by volume) as eluent, 26.8 g of 2-(4-trifluoromethoxyanilino)ethanol are obtained in the form of an orange-colored oil.
