The title compound, C10H9NO2, is almost planar (r.m.s. deviation for the non-H atoms = 0.027 Å) and the conformation across the C=N bond is syn. Further, the O atom of the benzofuran ring is syn to the CH3 group in the side chain. In the crystal, molecules are linked into C(3) chains propagating in [010] by O—HN hydrogen bonds.

In the title compound, C10H9NO3, the dihedral angle between the benzofuran ring system (r.m.s. deviation for the non-H atoms = 0.009 Å) and the –C—C(O)—N– segment is 83.76 (1)°. In the crystal, molecules are linked by N—HO and O—HO hydrogen bonds, generating (001) sheets, which feature C(4) and C(10) chains.
