In the title compound, C9H9N3OS, the plane of the benzene ring forms a dihedral angle of 33.40 (5)° with that of the triazole group. In the crystal, molecules are linked by O—H...N hydrogen bonds involving the phenol –OH group and one of the unsubstituted N atoms of the triazole ring, resulting in chains along [010]. These chains are further extended into a layer parallel to (001) by weak C—H...N hydrogen-bond interactions. Aromatic π–π stacking [centroid–centroid separation = 3.556 (1) Å] between the triazole rings links the layers into a three-dimensional network.

Evolution of the major spiroadduct obtained by cycloaddition of C,N-diphenylnitrone with 3-methylenephthalide in Zn/3 M HCl media gives a rearrangement product. The reaction did not stop at the formation of an aminoalcohol but was followed by dehydration; the title compound, C22H19NO2, was obtained after hydrogenation. It exists in the diastereoisomer SS/RR form. The packing is stabilized by weak N—H...O and C—H...O hydrogen-bond interactions.
