SYNTHESIS OF SOME IMIDAZO [ I , 2-b] [l , 2,4] TRIAZINE AND N-ALKYLATED IMIDAZO [l , 2-b] [1 , 2,4]-TRIAZINES

Abstract

A number of 3-amino-1, 2, 4-triazin-5 (2H)- ones(1) were synthesized and condensed with a-haloketones to give 2,6-disubstituted imidazo [1, 2-b] [1, 2, 4]-triazin-3 (4H)-ones (2). These compounds were reacted further with a - haloketones to yield N-alkylated products (3).
