Abstract
There are two molecules in the asymmetric unit of the title compound, C10H9N3, with inter-ring dihedral angles of 31.1 (1) and 35.3 (1)°. The bridging C—N—C bond angles are 128.2 (1) and 129.1 (1)°. In the crystal, the two independent molecules are linked into a dimer by two N—H⋯N hydrogen bonds.

Experimental
2-Chloropyrimidine (0.05 mol), aniline (0.05 mol) and ethanol (5 ml) were heated at 423–433 K for 3 h. The product was dissolved in water and the solution extracted with ether. The ether phase was dried over sodium sulfate; the evaporation of the solvent gave well shaped colorless crystals along with some unidentified brown material.
Refinement
Carbon-bound H-atoms were placed in calculated positions (C—H 0.95 Å) and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2Ueq(C). The amino H-atoms were located in a difference Fourier map, and were refined with a distance restraint of N–H 0.88±0.01 Å; their isotropic temperature factors were refined.
