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...[pi] and parallel slipped [pi]-[pi] interactions [centroid-centroid distance = 3.467 (1) Å; slippage 0.519 Å], forming a three-dimensional network.
