Abstract

In the structure of the title compound, C(20)H(15)BrN(4)O·C(2)H(6)O, the hydrogenated pyridinone ring adopts an envelope conformation. The dihedral angle between the bromo-substituted phenyl ring and the pyrazole ring is 79.6 (1)°, and that between the non-substituted phenyl ring and the pyrazole ring is 51.2 (1)°. In the crystal structure, mol-ecules are linked via inter-molecular N-H⋯O and O-H⋯N hydrogen bonds. A short inter-molecular N⋯Br contact [3.213 (4) Å] is present in the crystal structure.
