2-Methyl-3-(1H-pyrazol-3-yl)imidazo[1,2-a]pyrimidine.
In the title compound, C(10)H(9)N(5), the fused 2-methyl-imidazo[1,2-a]pyrimidine ring system is approximately planar [dihedral angle of 1.14 (9)° between the two fused rings] and the 1H-pyrazole ring is rotated by 28.16 (11)° out of that plane. In the crystal, the mol-ecules are linked into linear chains along the [100] direction by classical inter-molecular N-H⋯N hydrogen bonds.
