Modification of 3,5-dioxo-2-phenyl-2,3,4,5-tetrahydro-1,2,4-triazine-6-carbonitrile at position 4 is described. Alkylations were carried out under Mitsunobu reaction conditions in DCM or dioxane with alcohols containing tertiary amines, pyridine and imidazole heterocyclic systems, and Boc-protected amino groups. The scope of modifications was extended with arylations performed via Chan-Lam coupling reaction using copper(I) oxide as a catalyst in a DMF solution at room temperature. In order to further extend peripheral structural diversity the nitrile group at position 6 of several alkylated 1,2,4-triazines was transformed into the amidoxime functionality.
