Publication Abstract: 

 Directed lithiation of substituted pyridines containing a directing metalating group (DMG) with a lithium reagent in anhydrous solvent at low temperature gives the corresponding lithium intermediates in-situ, which on reactions with electrophiles produce the corresponding substituted derivatives. The method is simple, general, convenient and often high yielding
