Abstract

The five-membered ring of the title compound, C10H14NO, is almost planar [mean deviation from best plane = 0.006 (1) Å]. The N—O bond is in the plane of the five-membered ring. The mol­ecule is positioned about a pseudo-mirror plane at y = 0.375. In the crystal, mol­ecules are connected by inter­molecular C—H⋯O contacts into layers parallel to (010).
