Synthesis and structure of N,6-diaryl-4-methyl-2-cyanoimino-1,2,3,6-tetrahydropyrimidine-5-carboxamides

摘要

Reactions of acetoacetic acid N-arylamides with aromatic aldehydes and cyanoguanidine have led to the formation of N,6-diaryl-4-methyl-2-cyanoimino-1,2,3,6-tetrahydropyrimidine-5-carboxamides. Structure of the obtained compounds has been confirmed by IR, H-1 NMR spectroscopy, and X-ray diffraction data.
