Abstract
The title compound, C14H15FN2O2S, crystallizes with two mol-ecules in the asymmetric unit. In each mol-ecule, the pyrimidine ring adopts a sofa conformation with the sp (3)-hybridized C atom forming the flap and the fluoro-substituted ring in an axial position. In the crystal, mol-ecules are linked via N-H⋯S hydrogen bonds, forming chains of R 2 (2)(8) rings along [100]. In one independent mol-ecule, an intra-molecular C-H⋯O hydrogen bond is observed.
