Abstract
6-Aminonicotinic acid is reacted with an alkali carbonate selected from the group consisting of sodium carbonate and potassium carbonate. The reaction is carried out at elevated temperature and in dimethylformamide. The 6-aminonicotinic acid alkali salt so produced is reacted with 3-chloromethylpyridine hydrochloride. The reaction is carried out at elevated temperature and in dimethylformamide. The desired nicotinyl ester is thus produced.
