Abstract
Derivatives of 1-phenyl-2-amino-3-cyano-5-aryl-1H-pyrrole 4a-d were
synthesized by the reaction of phenacylmalononitrile derivatives 3a-d
with aniline in presence of conc HCl and ethanol under reflux1. Then, the
derivatives of 1-phenyl-2-amino-3-cyano-5-aryl-1H-pyrrole 4a-d were
refluxed with (85%) formic acid for 4h to afford derivatives of 6-aryl-7-
phenyl-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one 5a-d through the amide
intermediate (Scheme 1).
