The synthesis of ethyl 2-(2-acetyl-2-benzoyl-1-ethenyl)amino-3-dimethylaminopropenoate (4) from benzoylacetone (1) via 3-dimethylaminomethylenebenzoylacetone (2) and ethyl N-(2-acetyl-2-benzoyl-1-ethenyl)glycinate (3) and its transformation into 4-benzoyl-2-ethoxycarbonyl-3-methylpyrrole (9) is described. Cyclization of 4 into 9 represents a new synthesis of polysubstituted pyrroles.
