methods for site-selective lithiation of 1-(chlorophenyl)pyrroles and 1-(methoxyphenyl)pyrroles are described. Mono- or dilithiations are governed by change of both the temperature and the solvent from tetrahydrofuran to diethyl ether. Regioselectivities could be influenced by the quality of the metallating agent. Thus, 1-(4-chlorophenyl)pyrrole was dilithiated with activated butyllithium at 0 °C to
