The title compound, C 14 H 12 N 4 O 3 , a pyrazolopyrimidine derivative, displays normal geometrical parameters. The dihedral angle between the mean planes of the pyrazolopyrimidine unit and the phenyl ring is 26.14 (4) . The non-H atoms of the ester side chain are coplanar (r.m.s. deviation = 0.009
