Procedure

A mixture of (E)-4-(3-(3,5-dichloro-4-fluorophenyl)-4,4,4-trifluorobut-1-enyl)-2-(trifluoromethoxy)benzoic acid (0.25 g, 0.52 mmol), 2-amino-N-(2,2,2-trifluoroethyl)acetamide (0.158 g, 0.62 mmol), PyBOP (0.40 g, 0.78 mmol) and DIPEA (0.134 g, 1.04 mmol) in DCM (10.0 mL) were stirred at RT for 16 h. The reaction mixture was diluted with water and extracted with DCM. The combined DCM layer was washed with brine, dried over Na2SO4 and concentrated under reduced pressure. Purification by flash column chromatography (SiO2, 100-200 mesh; eluting with 20% ethyl acetate/pet ether) afforded the title compound as a pale yellow gummy material (0.15 g, 47%).
