1.2.4- Triazine-3,5,6-tricarboxylic acid, triethyl ester

ELECTRON-DEFICIENT HETEROCYCLIC AZADIENE TRIETHYL 1,2,4-TRIAZINE-3,5,6-TRICARBOXYLATE (1,2,4-Triazine-3,5,6-tricarboxylic acid, triethyl ester)... 

Tri ethyl 1,2,4-triazine-3,5,6-tri carboxyl ate 1,2,4-Tr1azine-3, 5, 6-tricarboxylic acid, triethyl ester (10) (74476-38-3)... 

It is worth noting that the C-N-C-C fragment can be derived from heterocyclic compounds. For instance, interaction of triethyl l,3,5-triazin-2,4,6-tricarboxylate 269 with arylhydrazines affords esters of 5-amino-6-oxo-l,6-dihydro-l,2,4-triazin-3-carboxylic acid 270 in good yields (Scheme 160) <2004TL2791>.
