    摘要： A new route for the preparation and purification of substituted 1,5-naphthyridine-3-carboxyamides, useful in the diagnosis and treatment of anxiety, Downs Syndrome, sleep, cognitive and seizure disorders, and overdose with benzodiazepine drugs and for enhancement of alertness, is provided. These compounds may be readily prepared by treating the corresponding 1,5-naphthyridine-3-carboxylic acids with a primary amine and a 1,1-carbonyldiimidazole. Purification is achieved by converting the substituted 1,5-naphthyridine-3-carboxyamides to a salt with a strong base such as potassium t-butoxide, recrystallizing and acidifying to regenerate the pure carboxyamide.
