Tegaserod hemimaleate is formed by reacting tegaserod with maleic acid, in a molar ratio of 2:1. Polymorphic crystalline forms of tegaserod hemimaleate are prepared by reacting tegaserod with maleic acid in ketone or tetrahydrofuran solvents.
Tegaserod hemimaleate是通过将tegaserod与maleic acid以2:1的摩尔比反应形成的。在酮或
四氢呋喃溶剂中反应tegaserod和maleic acid可以制备出多晶形态的tegaserod hemimaleate晶体。
