Versuchsvorschrift
Piperazine (1.2 g, 13.77 mM) was heated with 2-chloro-5-(trifluoromethyl)pyridine (0.5 g, 2.75 mmol) in THF (2 mL) for 2 hours. Subsequently the reaction mixture was poured onto crushed ice and extracted with ethyl acetate. The organic layer was washed with sodium bicarbonate and evaporated to furnish the required product.
