Ethyl 4-(3-butyrylthio-ureido)benzoate

Abstract

The title compound, C14H18N2O3S, crystallizes in the thio-amide form with an intra-molecular N - H⋯O hydrogen bond associated with the thio-urea unit. With the benzoic acid and the butyrylthio-ureido units, the mol-ecule consists of two planar building blocks connected by the common NH function adjacent to the aromatic ring. The inter-planar angle is 33.38 (3)°. Mol-ecules are connected in chains parallel to [110] by classical hydrogen bonds of the N - H⋯O type from the other NH group to the benzoate C=O of a neighboring mol-ecule. © 2008.
