The title compound, C17H19N5O2, features an almost planar purine skeleton (r.m.s. deviation = 0.009 Å) substituted by a tetra-hydro-furan ring, which adopts an envelope conformation. The purine and benzene rings subtend a dihedral angle of 66.70 (3)°. In the crystal, pairs of N-H⋯N hydrogen bonds connect adjacent mol-ecules into inversion dimers. C-H⋯N, C-H⋯O, C-H⋯π and π-π inter-actions [pyrimidine ring centroid-centroid distance = 3.3909 (1) Å] connect the dimers into a three-dimensional archi ...[more]
