Treatment of [1,3,5]triazine-2,4,6-tricarboxylic acid triethyl ester (4) with arylhydrazines provided 5-amino-6-oxo-1,6-dihydro[1,2,4]triazine-3-carboxylic acid ethyl esters 5a-g in moderate to good yields. Hydrolysis under basic conditions gave the corresponding free carboxylic acids 6a-d. Despite the relatively high number of heteroatoms present the amido as-triazine compounds 6a-d showed good solubility in phosphate buffer as determined by a lyophilization Solubility assay. building block 5a served as starting point for the syntheses of two discrete exocyclic 5-amido and 3-amido compound libraries 7 and 8. respectively.
