Multigram-Scale Synthesis of the Nav1.7 Inhibitor GDC-0310
This paper reports an improved, scalable, and practical multigram-scale synthesis of the selective Nav1.7 inhibitor GDC-0310 that eliminates the need for carbon monoxide-mediated alkoxycarbonylation, utilizes readily available starting materials for key fragments, and achieves a 23.5% overall yield with 99.71% purity through optimized key transformations.
