title: 1-[5-(2H-1,3-Benzodioxol-5-yl)-3-(4-methyl-phen-yl)-2-pyrazolin-1-yl]ethanone.
abstract: In the title compound, C19H18N2O3, the pyrazoline ring is close to being planar (r.m.s. deviation = 0.035 Å) and subtends dihedral angles of 2.11 (8) and 82.63 (8)° with the p-tolyl and benzene rings, respectively. In the crystal, C-H⋯O and C-H⋯N hydrogen bonds link the mol-ecules, forming a three-dimensional network. A weak C-H⋯π inter-action involving the benzene ring is also observed.
