The main precursor to the synthesis of new tri substituted Pyrroles (1&2) 4-( (z)-(E)-2,3,5-tri aryl allylidene amino)-N-(thiazole-2-yl) benzene sulfonamide (3&4). The last one was under went multicomponent witting reaction in presence of acid chloride and tri phenyl phosphine in basic media from tri ethyl amine to afford the substituted pyrrole named 4-(2,3,5-tri aryl-1H-pyrrole-1-yl)-N-(thiazole-2-yl) benzene sulfonamide (5a-g). The structure of prepared compounds were determined by the available physical and spectral methods M.
