1,2,4-Triazino[4,3-c]- and [2,3-c]quinazolines

This paper describes the reactions of 2-o-aminophenyl-1,4,5,6-tetrahydro-1-methyl-1,2,4-triazine with a variety of reagents to give substituted 1,2,4-triazino4,3-c]quinazolines or 1,2,4-triazino2,3-c]quinazolines. Certain representative compounds of these two new heterocyclic systems were characterized by the tlc, ir, nmr, mass spectra, and identified by unequivacol synthesis.
