The title compound, C10H5ClF2N2OS, was obtained by linking an amino heterocycle and a substituted benzoyl chloride. The dihedral angle between the two rings is 41.2 (2)° and the equalization of the amide C—N bond lengths reveals the existence of conjugation between the benzene ring and the thiazole unit. In the crystal, pairs of N—H...N hydrogen bonds link molecules into inversion dimers. Non-classical C—H...F and C—H...O hydrogen bonds stabilize the crystal structure.
