In the mol-ecule of the title compound, C(14)H(17)NO(2), the dihedral angle formed by the mean planes through the indan ring system and the amino-pentenone fragment is 83.26 (13)°. An intra-molecular N-H⋯O hydrogen bond is observed. In the crystal, mol-ecules are linked into one-dimensional chains extending along the [010] direction via O-H⋯O and C-H⋯O hydrogen bonds.
