Reaction Steps

Dissolve 5-fluoro-2-nitrobenzoic acid (15 g, 81.08 mmol) in anhydrous tetrahydrofuran (200 mL) and add dropwise with stirring at 20° C. a 1 molar solution of borane in tetrahydrofuran (243 ml, 243 mmol). Stir the mixture at 20° C. for 72 hours then add methanol (200 ml). Concentrate under reduced pressure and purify the residue by flash column chromatography (silica gel, 10-30% ethyl acetate/hexane) to obtain 13.92 g (100%) of the title compound as a white solid.
