Example 13 Preparation of (Z)-N-(2-oxo-2-((2,2,2-trifluoroethyl)amino)ethyl)-4-(1,4,4,4-tetrafluoro-3-(3,4,5-trichlorophenyl)but-1-en-1-yl)-2-(trifluoromethyl)benzamide (F1) To a 25 mL vial was added (Z)-4-(1,4,4,4-tetrafluoro-3-(3,4,5-trichlorophenyl)but-1-en-1-yl)-2-(trifluoromethyl)benzoic acid (C2) (0.105 g, 0.210 mmol) and dichloromethane (4 mL) to give a yellow solution. 2-Amino-N-(2,2,2-trifluoroethyl)acetamide hydrochloride (0.0610 g, 0.320 mmol) and benzotriazol-1-yl-oxytripyrrolidinophosphonium hexafluorophosphate (0.165 g, 0.320 mmol) were then added. Triethylamine (0.120 mL, 0.850 mmol) was added and the reaction mixture was stirred at room temperature overnight. The reaction mixture was then concentrated and purified by flash column chromatography providing the title compound as a yellow gum (0.105 g, 74%). The following compounds were prepared according to the procedures disclosed in Example 13:
