Abstract

In the title zwitterionic compound, C15H19NO2S, the six-membered heterocycle adopts a sofa conformation. The negative charge is delocalized along the carbonyl and enolate system on the ring and the positive charge is localized on the S atom. Two inter­molecular C—H⋯O inter­actions help to establish the packing.
