USPTO Abstract

Disclosed are improved methods for the synthesis of N-(8-[2-hydroxybenzoyl]- amino) caprylic acid. Certain compounds have been found useful for preventing the formation of a colored impurity when included in an ester hydrolysis reaction. Conducting ester hydrolysis in anaerobic conditions has also been found to minimize the formation of the color impurity. Also disclosed are improved methods for synthesizing the sodium salt of N-(8-[2-hydroxybenzoyl]-amino) caprylic acid.
