(2S)-2-{[(1S)-1-(4-bromophenyl)-2,2,2-trifluoroethyl]amino}-4,4-dichlorobutanoic acid (120 mg) and (1S)-1-cyano-2-(4-cyano-2-fluorophenyl)ethanaminium chloride (66 mg) were dissolved in DMF (1.5 ml) and HATU (223 mg) was added. The reaction mixture was stirred at room temperature for 5 min and Hunig's base (204 μL) was added. The solution was stirred for 18 hours. The mixture was poured onto an aqueous sodium hydrogen carbonate (saturated, 20 ml) and water (20 ml). The mixture was stirred in an erlenmeyer flask for 10 min. The aqueous layer was extracted with EtOAc. The organic layer was washed with brine, dried on MgSO4. It was concentrated under reduced pressure. The crude product was purified by flash (eluted with 20:80 to 55:45 EtOAc/hexanes).
