The disclosure encompasses a novel process for making piperidinone carboxamide indane and azainane derivatives, having less steps and improved yields as compared to previous synthetic methods for making these compounds, which are CGRP receptor antagonists, useful for the treatment of migrane. Conditions for an amide bond formation between an acid and amine include for example reacting the compounds of Formulae B (after salt break) and C with an amide coupling reagent and optionally an additive and an acid and/or a base in a non-reactive solvent.
该披露涵盖了一种用于制备哌啶酮羧酰胺茚和氮杂茚衍生物的新型过程,与以往的合成方法相比,该过程步骤更少,产率更高。这些化合物是CGRP受体拮抗剂,可用于治疗偏头痛。酰胺键形成的条件包括例如将化合物B(盐断裂后)和C与酰胺偶联试剂以及可选的添加剂和酸和/或碱在非反应性溶剂中反应。
