Water → 2,2,2-trifluoro-N-[2-(methylamino)ethyl]acetamide

Participants

Reaction Steps

A solution of N-methylethylenediamine (27.0 g, 364 mmol) and ethyl trifluoroacetate (96.6 mL, 812 mmol) in a mixture of ACN (350 mL) and water (7.8 mL, 436 mmol) was refluxed with stiffing overnight. Solvents were evaporated in vacuo. The residue was re-evaporated with i-PrOH (3×100 mL), followed by heat-cool crystallization from DCM (500 mL). Formed crystals were filtered, washed with DCM and dried in vacuo to provide compound AA (88.3 g, 85%) as white solid powder.
