Ethyl 4-(1,3-benzodioxol-5-yl)-6-methyl-2-sulfanylidene-1,2,3,4-tetrahydro- pyrimidine-5-carboxylate

Abstract

In the title compound, C15H16N2O 4S, 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. © Nayak et al. 2011.
