Abstract
Based on X-ray diffraction analysis, we have proved that the recently published results for ethyl 6-amino-5-cyano-4-aryl-1,4-dihydropyridine-3- carboxylate synthesis is in fact an environmentally friendly synthesis of 6-amino-5-cyano-4-aryl-4H-pyran derivatives using a multicomponent room-temperature grinding procedure of ethyl acetoacetate, [(2-aryl)methylene] malononitriles, and ammonium acetate.
