convergent synthesis and coupling of two key fragments, aniline 2 and carbamate 4-HCl, which serves as a masked isocyanate. To enable practical access to aniline 2, reduction of the corresponding nitroaromatic was designed to control potential mutagenic impurities. Key to the efficient preparation of 2 was the benzylic bromination of 8 followed by selective debromination of a gem-dibromide byproduct and subsequent
