Efficient and Simple Route for the Synthesis of N-(2-Pyridyl)-4-ethoxy-5-oxo-2,5-dihydro-1H-pyrrole-2,3-dicarboxylates
Three-component reaction of 2-aminopyridines, dialkyl acetylenedicarboxylates, triphenylphosphine, and ethyl chlorooxoacetate in the presence of triethylamine provides a sufficient route for the synthesis of dialkyl N-(2-pyridyl)-4-ethoxy-5-oxo-2,5-dihydro-1H-pyrrole-2,3-dicarboxylates in good yields.
