We report the development of a multifunctional reagent for the direct conversion of pyridines to Boc-protected 2-aminopyridines with exquisite site selectivity and chemoselectivity. The novel reagent was prepared on 200-g scale in a single step, reacts in the title reaction under mild conditions without precautions toward air or moisture, and is tolerant of nearly all common functionality. Experimental and in situ spectroscopic monitoring techniques provide detailed insights and unexpected findings for the unique reaction mechanism.
