To 3,3,3-trifluoropropanoic acid (136 mg, 1.06 mmol) in dry dichloromethane (10 mL) was added HATU (468 mg, 1.23 mmol) and diisopropylethylamine (580 μL, 3.35 mmol). The mixture was then stirred at room temperature for 10 min. 2-phenylbenzofuran-5-amine (234 mg, 1.12 mmol) was then added and the resulting mixture was stirred at room temperature for 48 h. Ethyl acetate was added and the organic layer was washed once with saturated aqueous water. The combined organic layers were dried over anhydrous MgSO4 and evaporated. The resulting solid was purified by column chromatography eluting using a gradient (ethyl acetate/hexanes 1:3 v/v to ethyl acetate/hexanes 1:1 v/v) followed by trituration in ethyl acetate to afford 99.3 mg (28%) of the title compound (LCMS RT=6.62 min)
