Abstract

The title compound, C(14)H(19)NO(4)S, was obtained in quanti-tative yield by Lewis acid-catalysed alcoholysis of a phtalimide precursor. An intra-molecular 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 mol-ecule. C-H⋯O inter-actions feature in the crystal structure.
