Procedure
To N,N-dimethylaminoethanol (25 mL) at 0° C. was added in small portion NaH 60% (4 mol eq, 0.465 g, 11.62 mmol) and after 10 min 2-chloro-6-trifluoromethyl-nicotinonitrile (0.6 g, 2.90 mmol) was slowly added. The mixture was heated at 65° C. for 4 h. Then the solvent was removed at reduced pressure, water was added and the aqueous phase was extracted with EtOAc (3×30 mL). The recombined organic phases were washed with brine, anhydrified over Na2SO4 and evaporated at reduced pressure to obtain a pale yellow oil (0.69 g, 2.66 mmol, 92% Yield) used for the next step of reaction without further purification.
