The manufacturing route toward verinurad, an amphoteric, class II atropisomer that readily forms solvates, has proven to be highly complex. This previously required the isolation of intermediates with challenging physical properties and the application of cryogenic processes. New processes were designed and optimized, enabling the manufacture of 113 kg of verinurad in its desired polymorphic form.
Verinurad 是一种容易形成溶剂化物的两性 II 类阻转异构体,其制造路线已被证明非常复杂。这以前需要分离具有挑战性物理特性的中间体和低温工艺的应用。设计和优化了新工艺,能够以所需的多晶型生产 113 公斤的 verinurad。采用了涉及合成、高通量实验、分析化学、结晶科学、计算机建模和工程的跨学科方法。对映异构体富集的 verinurad 盐的动力学测量证实消旋化发生在清除时间范围内,从而减轻了与 verinurad 中固有的轴向手性相关的安全问题。
