A New Synthesis of Calcium N-(5-Hydroxynicotinoyl)-L-glutamate and Its X-ray Diffraction Structure
A new synthesis of N-(5-hydroxynicotinoyl)-L-glutamic acid via a 5-hydroxynicotinic acid imidazolide intermediate has been developed. Its calcium salt (Ampasse) has been synthesized and its structure was studied by X-ray diffraction analysis. The reaction conditions for all stages of the process have been optimized and a method for the purification of the substance has been improved.
