Abstract
The asymmetric unit of the title compound, C17H17NO2, contains two crystallographically independent molecules. Both molecules adopt a trans configuration about the C=C bond, with the C—C=C—C fragments in the two molecules twisted in opposite directions [torsion angles of 174.2 (2) and −175.8 (2)°]. The two benzene rings in each of the molecules make dihedral angles of 20.21 (6) and 48.64 (4)°. In the crystal, adjacent molecules are linked by O—H⋯O hydrogen bonds into infinite polymeric chains.

The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry
