Crystal structure of ethyl 6-chloro-methyl-2-oxo-4-(2,3,4-tri-meth-oxy-phen-yl)-1,2,3,4-tetra-hydro-pyrimidine-5-carboxyl-ate.
In the title compound, C17H21ClN2O6, the di-hydro-pyrimidine ring adopts a flattened envelope conformation, with the sp (3)-hybridized C atom forming the flap. The dihedral angle between the least-squares planes of the benzene and di-hydro-pyrimidine rings is 88.09 (6)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring. 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, and the dimers are linked via further pairs of N-H⋯O hydrogen bonds, forming R 2 (2)(14) rings and chains of mol-ecules along [111]. Pairs of inversion-related chains are linked via weak C-H⋯π inter-actions.
