2-[(4-Chloro­benz­yl)sulfanyl]-4-(2-methyl­prop­yl)-6-[3-(trifluoro­meth­yl)anilino]­pyrimidine-5-carbonitrile

Three independent mol-ecules comprise the asymmetric unit of the title compound, C(23)H(20)ClF(3)N(4)S. The conformations of the mol-ecules are similar with the chloro-benzene and CF(3)-benzene rings almost perpendicular to, and almost co-planar with, the pyrimidinyl ring [range of dihedral angles = 80.36 (13)-88.07 (14) and 11.89 (14)-23.30 (14)°, respectively]; the benzene rings are roughly orthogonal to each other [64.81 (16)-72.16 (15)°]. In the crystal, two of the independent mol-ecules associate via weak N-H⋯N(cyano) hydrogen bonds and 12-membered {⋯HNC(3)N}(2) synthons; the third independent mol-ecule self-associates similarly but about a centre of inversion. The sample studied was found to be a non-merohedral twin and the minor twin component refined to 47.16 (7)%.
