EDC (1.3 equiv.) was added to a solution of 3-bromo-4-(hydroxymethyl)benzoic acid (1.0 equiv), 3-(trifluoromethyl)aniline (1.1 equiv.), HOAt (1.3 equiv.) in DMF (0.43 M). The mixture was stirred at ambient temperature 3 hrs. The reaction mixture was diluted with water and extracted with ethyl acetate. The combined extracts were washed sequentially with 1M aqueous sodium hydroxide and brine, dried over sodium sulfate, filtered, and concentrated. The residue was purified by ISCO(50% EtOAc/Heptane) to yield 3-bromo-4-(hydroxymethyl)-N-(3-(trifluoromethyl)phenyl)benzamide in 35% yield. LC/MS (m/z)=374.0 (MH+), Rt=0.93 min.
