Abstract
The molecule of the title compound, C19H23N5O3, contains six-membered pyrimidine and five-membered imidazole rings merged into the essentially planar purine skeleton (r.m.s. deviation = 0.01 Å). In the crystal, pairs of N—H⋯N hydrogen bonds link molecules into inversion dimers. The dimers are linked via C—H⋯O hydrogen bonds, forming double-stranded chains propagating along [001]. These chains are linked via C—H⋯π and parallel slipped π–π interactions [centroid–centroid distance = 3.467 (1) Å; slippage 0.519 Å], forming a three-dimensional network.
