Abstract:
The fused pyrazole and pyrimidine rings in the title compound, C22H19BrN4O, are almost coplanar, their planes being inclined to one another by 2.08 (13)°. The dihedral angles formed by the mean plane of the fused ring system and the phenyl and benzene rings are 16.21 (4) and 82.84 (4)°, respectively. An intra-molecular N-H⋯N hydrogen bond is observed. In the crystal, mol-ecules form inversion dimers via pairs of C-H⋯O hydrogen bonds. π-π inter-actions, with centroid-centroid distances of 3.4916 (9) Å, connect the dimers into a three-dimensional network.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
