Abstract

In the title compound, C18H15N3O2, the benzo-furan ring system is essentially planar, the rings making a dihedral angle of 0.57 (9)°. The phenyl, furan and benzene rings subtend dihedral angles of 47.07 (10), 85.76 (7) and 86.04 (7)°, respectively, with the pyrazole ring. In the crystal, mol-ecules are linked by weak N-H⋯N, N-H⋯O and C-H⋯O inter-actions, generating edge-fused R 4 (4)(20), and R 1 (2)(7) rings linked into sheets which are parallel to (010).
