✦ Synopsis

In the title compound, C~12~H~14~ClN~5~O~4~, the dihedral angles between the purine plane and two methoxycarbonyl planes are 15.806 (19) and 68.818 (18)°. Intermolecular N—H...O and N—H...N hydrogen bonds link molecules into bands along the b axis; they are further aggregated via C—H...O interactions into layers parallel to the ab plane.
