چکیده
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.

In the title compound, C(18)H(19)ClN(4)O(3), the dihydro-pyrimidin-one ring adopts a flattened boat conformation. The dihedral angle between the phenyl and pyrazole rings is 43.39 (6)°. An intra-molecular C-H⋯O contact generates an S(8) ring motif that stabilizes the mol-ecular conformation and precludes the carbonyl O atom of the ester group from forming inter-molecular inter-actions. Mol-ecul...

The asymmetric unit of the title compound, C(20)H(18)F(2)N(2)O(2)S, contains four independent mol-ecules, two of which are paired into a dimer by way of two N-H⋯S hydrogen bonds. The other two independent mol-ecules are paired into two centrosymmetric dimers via pairs of inter-molecular N-H⋯S hydrogen bonds. In one mol-ecule, the carboxyl-ate O atoms, methyl-ene and methyl groups attached to th...
