Versuchsvorschrift

In step (2) of Reaction Scheme III, a 2-chloro-3-nitropyridine of Formula XXIX-4 or XXIX-5 is reacted with sodium phenoxide to provide a 3-nitro-2-phenoxypyridine of Formula XXX-4 or XXX-5. Phenol is reacted with sodium hydride in a suitable solvent such as diglyme (bis(2-methoxyethyl) ether) to form the phenoxide. The phenoxide is then reacted at an elevated temperature with a compound of Formula XXIX-4 or XXIX-5. The product can be isolated from the reaction mixture using conventional methods.
