In the title compound, C12H12N2O, the azetidine ring (r.m.s. deviation = 0.021 Å) and the oxetane ring (r.m.s. deviation = 0.014 Å) are nearly perpendicular to each other [dihedral angle = 89.7 (1)°]. The azetidine ring is twisted out of the plane of the benzene ring by 18.3 (1)°. In the crystal structure, molecules are linked to form chains along the c axis by C—H⋯O hydrogen bonds.
The title compound is a key intermediate to synthesize (pyrrolo[3,4-c]pyrazol-3-yl)benzamide derivatives. For the anti-tumor effect of these derivatives, see: Fancelli et al. (2005 ▶).
