Mannich Reaction Involving 6-Amino-4-methyl-2-(thio)oxo-1,2-dihydropyridine-3,5-dicarbonitriles
The reaction of (1-ethoxyethylidene)malononitrile with cyanoacetamide or cyanothioacetamide has yielded 6-amino-4-methyl-2-(thio)oxo-1,2-dihydropyridine-3,5-dicarbonitriles. The resulting pyridine derivatives enter into the aminomethylation reaction with an excess of formaldehyde and primary amines...
