Abstract: There are two independent molecules in the asymmetric unit of the title compound, C21H21N5O2. In each molecule, the indolizine ring system is essentially planar, with r.m.s. deviations of 0.030 and 0.028 Å. The dihedral angles between the indolizine ring system and the pyrazole rings are 54.7 (3) and 8.6 (3)° in one molecule and 54.4 (3) and 6.6 (3)° in the other. In the crystal, weak C-H...O and C-H...N hydrogen bonds link molecules, forming a two-dimensional network parallel to (100).
