Abstract: In the title compound, C₁₁H₁₁NO₂, the cyclopentene ring is planar to within 0.025  (2)  Å. The dihedral angle between the cyclopentene plane and the pyridine ring plane is 83.1  (1)°. Strong intermolecular O-HN hydrogen bonds link the molecules into a chain which runs parallel to the a axis and has a graph-set motif of C(5). Weak C-HO interactions form a three-dimensional network in the crystal stucture.
