2.5 g of 3-Amino-4-trifluoromethyl-benzoic acid were dissolved using 50 ml of diethyl ether and 25 ml of methanol. Then, 6.1 ml of a 2M solution of trimethylsilyldiazomethane in hexane were added at 10-20° C. The reaction mixture was stirred at room temperature for 1 h. Then, 6.1 ml of a 2M solution of trimethylsilyldiazomethane in hexane were added at 10-20° C. The reaction mixture was stirred at room temperature for 1 h. The reaction mixture was then evaporated. Chromatography on silica gel using EA/HEP 1:2 yielded 2.3 g of the title compound, viscous oil.
