Abstract
Ethyl 4-ethoxycarbonylmethyl-3,5-dimethylpyrrole-2-carboxylate (1) has been synthesized by extension and modification of Knorr pyrrole synthesis. Its acetoxymethyl derivative (2) has also been synthesized. Diethyl 3,3'-bis(ethoxycarbonylmethyl)-4,4'-dimethyl-2,2'-dipyrrylmethane-5,5'-dicarboxylate has been synthesized by self-condensation of 2.
