Reaction Steps

4-Amino-3-(trifluoromethoxy)benzoic acid 2.0 g (9.04 mmol) is dissolved in 50 mL of THF. Lithium aluminium hydride (1.4 g, 36.2 mmol) is added portionwise over 10 minutes. A reflux condensor is attached and the reaction mixture is refluxed for 6 h at 80° C. It is cooled to room temperature and the Fieser work up is performed (1.4 mL of water, 1.4 mL 15% NaOH, 4.2 mL of water). The granular inorganic precipitate is filtered and washed with THF. The organic fractions is combined and dried over anhydrous Na2SO4. The solvent is evaporated and the residue is purified on silica, eluting with 0-10% methanol/dichloromethane to give the title compound (1.2 g, 5.79 mmol 64%). (ESMS): ink 208.3 (M+H+).
