Abstract: In the crystal of the title compound, C13H20N4, the molecule is nearly planar, the dihedral angles between the pyrimidine and the two pyrrolidine rings being 4.71 (2) and 4.50 (2)°. The crystal features inversion-related dimers linked by pairs of C-HN hydrogen bonds generating R22(16) patterns. The dimeric units are further linked into C(6) chains via an additional C-HN hydrogen bond.
