Reaction Steps

Propargyl amine (4.00 g, 72.62 mmol, 1.00 equiv.) was added dropwise to methyl trifluoroacetate (11.16 g, 87.15 mmol, 1.20 equiv.) at 0° C. The reaction mixture was stirred at 0° C. for 2 h and then concentrated under reduced pressure to remove methanol. The product was purified by vacuum distillation yielding propargyltrifluoroacetamide as a colorless liquid (9.59 g, 87%). The structure was confirmed by 1H- and 19F-NMR.
