New functionalized amino derivatives of 2-hydroxyphenyl-1,3,5-triazines

4-(2-Hydroxyphenyl)-1,3,5-triazin-2-ylcyanamides reacted with sodium azide to give N-(tetrazol-5-yl)-1,3,5-triazin-2-amines, and their reaction with allyl bromide afforded allyl(1,3,5-triazin-2-yl)cyanamides. Acetylation of 4-(2-hydroxyphenyl)-1,3,5-triazin-2-amines involved only the amino group with formation of diacetylamino derivatives, whereas the phenolic hydroxy group remained intact. The reaction of triazinamines with 2,5-dimethoxytetrahydrofuran in the presence of P₂O₅ gave pyrrolyl-substituted triazines.
