Procedure

To a solution of 3-amino-5-(trifluoromethyl)benzoic acid (0.25 g, 1.22 mmol) in DMF (3 mL) is added HOBt (0.494 g, 3.66 mmol) followed by HATU (0.695 g, 1.83 mmol), propan-2-amine (0.311 mL, 3.66 mmol) and DIEA (0.96 mL, 5.48 mmol). After stirring at it overnight the solution is concentrated and the residue is dissolved in EtOAc, washed with sat aq NaHCO3, brine, and dried over Na2SO4. Following concentration the residue is carried on to next step without further purification. MS (ESI) m/z 247.1 (M+1).
