Ethyl 2-[N-(tert-butylsulfinyl)carbamoyl]benzoate

Abstract

The title compound, C14H19NO4S, was obtained in quantitative yield by Lewis acid-catalysed alcoholysis of a phtalimide precursor. An intramolecular C—H...O hydrogen bond occurs. In the crystal, centrosymmetric dimers are formed by pairs of N—H...O hydrogen bonds between the sulfinyl O atoms and the carbamoyl N—H group of a neighboring molecule. C—H...O interactions feature in the crystal structure.
