Abstract

In the title compound, C14H11F2N3S, the heterocyclic five-membered ring has an envelope conformation. Although the mol­ecule is chiral, the compound is a racemate (R/S). There is a weak inter­molecular C—H⋯π inter­action but no classical hydrogen bonds are observed in the crystal structure.
