Abstract

The title compound, C(16)H(12)N(4)O(2), is a functionalized triazoloquinazoline with a substituted benz-yloxy group attached at the 2-position of a triazole spacer. The triazoloquinazoline fused-ring system is approximately planar (r.m.s. deviation = 0.016 Å) while the benzyl substituent is perpendicular to the ring system, making a dihedral angle of 65.29 (6)°. The phenyl ring of the benz-yloxy moiety is equally disordered over two sets of sites. A centrosymmetric N-H⋯N hydrogen bond connects mol-ecules into dimers.
