چکیده
In the title compound, C(15)H(16)N(2)O(4)S, the dihedral angles between the planes of the benzodioxole and ester groups and the plane of the six-membered tetra-hydro-pyrimidine ring are 89.5 (1) and 20.2 (1)°, respectively. Inter-molecular N-H⋯S hydrogen bonds assemble the mol-ecules into dimers, which are further connected via N-H⋯O inter-actions into chains parallel to [010]. Weak C-H⋯S and C-H⋯π inter-actions enhance the stability of the crystal structure.

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...
