Abstract
The present disclosure provides methods of synthesizing a compound of Formula (P)-I. The method proceeds through several different pathways including several novel chiral separations, a Sonogashira coupling, a zinc mediated reductive cyanation, as well as through various halide containing intermediates. Also disclosed is the multi-kilogram preparation of several novel intermediates.
