N-{2-[4-(2-Methoxyphenyl)piperazin-1-yl]ethyl}pyridin-2-amine monohydrate

In the title compound, C18H24N4O H2O, the piperizine ring adopts a chair conformation and the dihedral angle between the phenyl and pyridine rings is 39.9 (3) . The comformations of the attachment of the anisole and N-ethylpyridin-2-amine groups to the piperazine ring are +antiperiplanar. An intramolecular C—H O interaction occurs. In the crystal, the water molecule links the molecules into chains through O— H N hydrogen bonds. Weak N—H O, C—H N and C— H O interactions further stabilize the crystal structure.
