Abstract:
The title compound, C(10)H(16)N(4), crystalizes with two mol-ecules (A and B) in the asymmetric unit in which the dihedral angles between the piperidine and pyrimidine rings are 47.5 (1) and 10.3 (1)°. The four C atoms of the pyrimidine ring in one of the mol-ecules are disordered over two sets of sites with occupancy factors 0.508 (11):0.492 (11). In the crystal, the A mol-ecules are linked to one another through N-H⋯N hydrogen bonds, generating R(2) (2)(8) ring patterns and forming inversion dimers. These dimers are further connected on either side to a B molecule through pairs of N-H⋯N hydrogen bonds, resulting in a tetra-meric unit.

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.
