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 migraine. 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.
该披露涵盖了一种制备哌啶酮羧酰胺吲哚和氮杂吲哚衍生物的新工艺,与以前用于制备这些化合物的合成方法相比,该工艺步骤更少且产率更高,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公式B(盐断后)和C的化合物与酰胺偶联试剂以及非反应性溶剂中的可选添加剂和酸和/或碱反应。
