Abstract:
In the title compound, C(14)H(11)F(2)N(3)S, the heterocyclic five-membered ring has an envelope conformation. Although the mol-ecule is chiral, the compound is a racemate (R/S). There is a weak inter-molecular C-H⋯π inter-action but no classical hydrogen bonds are observed in the crystal structure.
