To a solution of 4-hydroxy-2-(trifluoromethyl)benzoic acid (4.62 g, 22.4 mmol, Fluorochem) in THF (60 ml) at ambient temperature under nitrogen was added dropwise 1.0 M borane-tetrahydrofuran complex (48 ml, 48.0 mmol). The solution was heated to 80° C. for 2 h. To the solution at ambient temperature was added methanol dropwise (40 ml). The solution was heated to 80° C. for 30 min. The solvent was removed in vacuo and the residue dissolved in methanol (100 ml). The solvent was removed in vacuo to leave the title compound as a white solid (4.39 g);
