Paragraph 0026-0053, (2019/10/02)
The invention provides a method for preparing a saxagliptin intermediate 2 as shown in the specification. An existing process is improved by using the method, so that the yield and purity of a productare greatly increased, in addition, it is convenient realize aftertreatment, and the method is particularly suitable for industrial production.
Method for synthesizing Saxagliptin and intermediate

Paragraph 0070; 0071; 0072; 0073, (2016/11/24)
A method for synthesizing Saxagliptin and its intermediate is disclosed. According to the method, propylphosphonic anhydride is used in a peptide coupling reaction and a dehydration reaction of formamide, thus reducing side reaction of racemization and decreasing toxicity of aftertreatment; and ethylene glycol diethyl ether is preferably used as a solvent in the dehydration reaction of formamide, thus increasing reaction temperature of propylphosphonic anhydride dehydration and shortening reaction time so as to reduce side reaction of racemization.
