Reaction Steps

4-methoxypyridine-2,6-dicarboxamide (900 mg, 4.6 mmol) was mixed with trifluoroacetic anhydride (2.32 g, 11.1 mmol) and pyridine (1.6 g, 20.2 mmol) in dichloromethane (20 mL) and stirred overnight at room temperature. The reaction mixture was diluted with dichloromethane and washed with water. Standard work up, afforded 461 mg of 2,6-dicyano-4-methoxypyridine.2,6-Dicyano-4-methoxypyridine (460 mg, 2.89 mmol) and 5M hydroxylamine hydrochloride (0.578 mL, 2.89 mmol) in ethanol (3 mL) and 1N sodium hydroxide (2.89 mL, 2.89 mmol), were stirred at room temperature overnight. Standard work up afforded 180 mg (32.4%) of 6-cyano-4-methoxypyrid-2-yl-amidoxime.
