The dihydrobenzothiazine ring is distinctly folded across the S⋯N axis and a puckering analysis of its conformation was performed. In the crystal, two sets of weak C—HPh⋯ODbt (Ph = phenyl and Dbt = dihydrobenzothiazine) hydrogen bonds form layers parallel to the bc plane. The layers stack along the a-axis direction with intercalation of the ester chains.
