Ethyl 4-(2-bromo-5-fluorophenyl)-6-methyl-1-phenyl-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate

In the title molecule, C20H18BrFN2O2S, 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)degrees], while the other phenyl ring is oriented at an angle of 85.14 (5)degrees. The ethoxy group is disordered over two orientations with site occpancies of ca 0.869 (4) and 0.131 (4). Intramolecular C-H center dot center dot center dot Br and C-H center dot center dot center dot O hydrogen bonds generate S(5) and S(6) ring motifs. The crystal structure is stabilized by intermolecular N-H center dot center dot center dot S, C-H center dot center dot center dot F, C-H center dot center dot center dot O and C-H center dot center dot center dot Br hydrogen bonds.
