چکیده
In the title compound, C14H14Cl2N2O3, the chloro-phenyl ring makes a dihedral angle of 87.08 (9)° with the tetra-hydro-pyrimidine ring. There is a short intra-molecular C-H⋯O contact present. In the crystal, mol-ecules are linked via pairs of N-H⋯O hydrogen bonds, forming inversion dimers with an R (2) 2(8) ring motif. The dimers are linked via a second pair of N-H⋯O hydrogen bonds, this time enclosing an R (4) 4(20) ring motif, forming ribbons along [100]. The ribbons are linked via C-H⋯O hydrogen bonds, forming sheets lying parallel to (001). The terminal ethyl group is disordered over two positions with an occupancy ratio of 0.654 (17):0.346 (17).
