Reaction Steps
To methylene chloride (50 mL) cooled in an ice bath was added pentafluoropyridine (2.0 g, 11.8 mmol) and dimethylamine (2.97 mL of a 40% solution in water, 24 mmol). After stirring for 30 minutes the solution was washed with water, and dried over basic alumina. The solvent was removed in vacuo to give 4-dimethylamino-2,3,5,6-tetrafluoropyridine; NMR (CDCl3) 3.13 (m, 6) ppm.
