In the title compound, C15H13N3O, the pyrrolyl and phenyl rings make dihedral angles of 58.99 (5) and 34.95 (5)degrees, respectively, with the central pyrazole ring. In the crystal, weak, pairwise C-H center dot center dot center dot O interactions across centers of symmetry form dimers, which are further associated into corrugated sheets running approximately parallel to (100) via weak C-H center dot center dot center dot N interactions.
