Pentafluoropyridine was used as the starting material for the preparation of a range of pyridine derivatives that bear five different substituents. In this context, syntheses of penta-functional pyridine systems by sequences of nucleophilic aromatic substitution, palladium catalysed coupling and bromo-lithiation processes are described.
