Regioselective ortho lithiation of halopyridines
Gribble, Gordon W.,Saulnier, Mark G.
, p. 4137 - 4140 (1980)
Regioselective ortho lithiation of 2-, 3-, and 4-halopyridines is achieved with lithium diisopropylamide (-78°, tetrahydrofuran) to afford, upon quenching with electrophilic reagents, 2,3- and 3,4-disubstituted pyridines in good to excellent yield.
