Popis: In the title compound, C15H14N4O2, the triazolopyrimidine ring system is almost planar (r.m.s. deviation = 0.02 Å) and the phenyl ring is inclined to its mean plane by 42.45 (9)°. The carboxyl group is inclined to the triazolopyrimidine ring mean plane by 57.8 (3)°. In the molecule, there is a short C—H...O contact involving the carbonyl O atom and an H atom of the adjacent methyl substituent. In the crystal, neighbouring molecules are linked by C—H...O hydrogen bonds, forming chains propagating along [010]. There are also weak π–π interactions present involving the pyridine and phenyl rings of neighbouring chains [intercentroid distance = 3.8580 (16) Å].
