A process is provided for preparing the dipeptidyl peptidase of the structure (I) (also referred to as saxaglipitin) by direct dehydration, in one pot, of the amide II (II) by reacting amide II with phosphorus oxychloride in an organic solvent such as dichloromethane, quenching the reaction mixture with water to form the hydrochloric acid salt of I, and treating the hydrochloric acid salt with base to form the free base of I.
提供了一种制备结构式(I)的二肽酶(也称为萨格列普汀)的方法,通过在有机溶剂如二氯甲烷中,将酰胺II(II)直接脱水反应制备。反应结束后,用水淬灭反应混合物以形成I的盐酸盐,并用碱处理盐酸盐以形成I的自由碱基。
