In the title compound, C17H16N2O2S, the dihedral angle between the benzothiazole ring system and the benzene ring is 1.20 (2)°. The substituted amino substituent is in an extended conformation with an N-C-C-O torsion angle of 179.4 (3)°. In the crystal structure, pairs of molecules are connected by intermolecular N-HO and weak C-HO hydrogen bonds, forming centrosymmetric dimers.
