Ethanamine, 2,2,2-trifluoro- → Ethyl (E)-3-[2-(2,2,2-trifluoroethylcarbamoyl)-5-trifluoromethylphenyl]acrylate

Participants

Reaction Steps

1.3 g of 2-(2-ethoxycarbonylvinyl)-4-trifluoromethylbenzoic acid (4.5 mmol) and 453 mg of 2,2,2-trifluoroethylamine (4.5 mmol) were dissolved in 5 ml of DMF and 0.93 g of DCC was added. The mixture was stirred at RT for 4 h. The urea by-product was removed by filtration and then the solvent was removed under reduced pressure. The residue was recrystallized from DIP to obtain 1.6 g (96%) of white crystals.
