Reaction Steps

A slurry of 4-acetylamino-3-chloro-6-(4-cyano-2,6-difluoro-3-methoxyphenyl)pyridine (0.13 g, 0.33 mmol) in methanol (5 mL) was treated with 1N sodium hydroxide (1.7 mL) and stirred at ambient temperature for 1 hour. The solution was diluted with water (15 mL) and acidified with 1N hydrochloric acid (1.7 mL) and the solid collected (0.095 g). Analysis by 1H NMR showed the 4-amino-3-chloro-6-(4-cyano-2,6-difluoro-3-methoxyphenyl)pyridine-2-carboxylic acid and an impurity. This material was used without further purification.
