title: Ethyl 4-(2-bromo-5-fluoro-phen-yl)-6-methyl-1-phenyl-2-thioxo-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.
abstract: In the title mol-ecule, C(20)H(18)BrFN(2)O(2)S, the pyrimidine ring adopts a flattened envelope conformation. The halogenated benzene ring is orthogonal to the planar part of the pyrimidine ring [dihedral angle = 89.05 (4)°], while the other phenyl ring is oriented at an angle of 85.14 (5)°. The ethoxy group is disordered over two orientations with site occpancies of ca 0.869 (4) and 0.131 (4). Intra-molecular C-H⋯Br and C-H⋯O hydrogen bonds generate S(5) and S(6) ring motifs. The crystal structure is stabilized by inter-molecular N-H⋯S, C-H⋯F, C-H⋯O and C-H⋯Br hydrogen bonds.
