Abstract:
A process for preparing a pure alanylglutamine comprises the steps of: 1) reacting N-(α-chloro)-propionyl-glutamine and hydrazine compound to obtain an alanylglutamine crude product; 2) mixing anhydrous methanol and the alanylglutamine crude product to provide a filter cake; 3) dissolving the filter cake in water, heating, adding ethanol, and cooling to yield the pure alanylglutamine.
