Potassium Carbonate → 2-chloro-N-[1-((6-chloropyridin-3-yl)methyl)pyridin-2(1H)-ylidene]-2,2-difluoroacetamide

Participants

Reaction Steps

An amount of 53 mg (0.33 mmol) of 2-chloro-5-chloromethylpyridine dissolved in 6 mL of anhydrous acetonitrile was added to 68 mg (0.33 mmol) of 2-chloro-2,2-difluoro-N-(pyridin-2(1H)-ylidene)acetamide synthesized by the above method, following which 50 mg (0.36 mmol) of potassium carbonate was added and refluxing under heating was carried out for 1 hour. Following reaction completion, the reaction mixture was returned to room temperature then concentrated under reduced pressure. Diethyl ether was added to the concentrate, whereupon a solid separated out. The solid was collected by filtration and dried, affording the target compound in an amount of 49 mg (yield, 45%).
