N,N-Diethylaniline → HCID 21716192, compound

Participants

Reaction Steps

2.78 g (7.73 mmol) of 3-[4-chloro-2-fluoro-6-propargyloxyphenyl]-1-methyl-6-trifluoromethyl-2(1H)-pyridone and 2.35 g (15.46 mmol) of cesium fluoride was heated to 180° C. in 50 ml of N,N-diethylaniline and reacted for 1 hour. The solvent was distilled off under reduced pressure, followed by extraction with ethyl acetate. The organic layer was washed with dilute hydrochloric acid and dried over magnesium sulfate. Then, the solvent was distilled off under reduced pressure. Then, the obtained residue was purified by silica gel column chromatography to obtain 0.58 g (yield: 21%) of the desired product. Melting point: 138-140° C.
