In the title compound, C14H13NO4S·C3H7NO, the C—S—N—C torsion angle of −64.55 (17)° defines the folded conformation of the molecule. The dihedral angle between the benzene rings is 83.367 (6)°. In a crystal, molecules are linked into a chain along a axis through intermolecular N—H⋯O and O—H⋯O hydrogen bonds. There is also an intramolecular C—H⋯π interaction.
N-protected amino acids possess an R-CONH-R′ group analogous to the structure of O-terminal peptides and proteins, see: Antolini et al. (1984 ▶); Menabue & Saladini (1988 ▶).
