The first reported solid-phase synthesis of 3-amino-1,2,4-triazin-5(4H)-ones is described. Reactions of polymer-bound isothiourea with 2,3-diaza-3-pentenedioic anhydride forms 3-amino-1,2,4-triazin-5(4H)-ones in good yields and high purity.

4-Aryl-5-oxo-3-alkylmercapto-1,2,4-triazine derivatives undergo interesting reaction with ammonia to give mainly, instead of the expected corresponding 3-amino derivatives, the 3-arylamino-2,5-dihydro-5-oxo-1,2,4-triazines.In this reaction 4-aryl-3,5-diox

The action of hydrazine on 3-methylmercapto-5-oxo-4-aryl-4,5-dihydro-1,2,4-triazines led to a novel rearrangement and gave 3-arylamino-4-amino-5-oxo-4,5-dihydro-1,2,4-triazines.The mechanism of this rearrangement was discussed.
