2-[5-(2,3-Di­meth­oxy­naphthalen-1-yl)-4,5-di­hydro-1H-pyrazol-3-yl]-3-meth­oxy­phenol

In the title compound, C(22)H(22)N(2)O(4), the central pyrazoline ring exhibits a nearly planar structure (r.m.s. deviation = 0.025 Å) despite having two sp (3) carbon atoms. The pyrazoline ring subtends dihedral angles of 4.61 (1) and 87.31 (1)° with the pendant benzene ring and naphthalene ring system, respectively. The dihedral angle between the planes of the benzene ring and the naphthalene ring system is 89.76 (2)°. An intra­molecular O—H⋯N hydrogen bond forms an S(6) ring motif. In the crystal, inversion dimers formed by pairwise weak N—H⋯N hydrogen bonds generate R (2) (2)(4) loops and the dimers are linked by pairwise C—H⋯O hydrogen bonds [which generate R (2) (2)(8) loops] into [100] chains.
