N-(4-Acetyl-3-methyl-1-phenyl-1H-pyrazol-5-yl)-N-methyl-2-(2-methyl-4-oxo-3,4-dihydroquinazolin-3-yl)benzamide

In the title compound, C₂₉H₂₅N₅O₃, the dihedral angle between the benzene ring and the pendant quinazoline ring system (r.m.s. deviation = 0.036Å) is 87.60 (17)°. The equivalent angle between the pyrazole ring and the phenyl group is 70.0 (2)°. The dihedral angle between the benzene and pyrazole rings is 30.7 (2)° and overall, the mol­ecular conformation approximates to a Z shape. A short intra­molecular C—H...O contact occurs. In the crystal, the mol­ecules are linked by Cπ—H...O-type hydrogen bonds and aromatic π–π stacking inter­actions [centroid–centroid distance = 3.860 (3) Å], generating a three-dimensional network.

(E)-2-{[1-(3,11-Dimethyl-4-methyl­ene-10-oxo-1-phenyl-4,5,10,11-tetra­hydro-1H-benzo[b]pyrazolo­[3,4-f][1,5]diazo­cin-5-yl)ethyl­idene]amino}-N-methyl-N-(3-methyl-1-phenyl-1H-pyrazol-5-yl)benzamide

The central eight-membered ring of the title compound, C₄₀H₃₆N₈O₂, deviates from the ideal boat conformation because the bond between the exo-ethyl­ene group and the adjacent N atom is twisted by 60.0 (4)° due to steric hindrance. Its adjacent benzene and pyrazole rings are oriented almost perpendicular to each other, making a dihedral angle of 85.8 (3)°. In the crystal, the mol­ecules are linked by C(ar)—H...O hydrogen bonds, generating a three-dimensional network.
