Methyl 2-benzyl-4-hy­droxy-1,1-dioxo-1,2,3,4-tetra­hydro-1λ(6),2-benzothia­zine-3-carboxyl­ate

In the title compound, C(17)H(15)NO(5)S, the benzene ring of the fused-ring system is twisted by 11.67 (6)° with respect to the thia­zine ring. The atoms of the four-atom methyl ester group and the phenyl ring of the benzyl unit are inclined at 16.50 (7) and 44.52 (3)° with respect to the thia­zine ring. An intra­molecular O—H⋯O hydrogen bond gives rise to a six-membered S(6) ring motif. In the crystal, mol­ecules are extended through a C—H⋯O inter­action along the a axis. C—H⋯π inter­actions are also observed.
