Abstract: In the title compound, C16H19ClN4O3, the cyclohexane ring displays a chair formation and the tetrahydropyridine ring displays an envelope conformation with the methylene C atom as the flap; the imidazolidine ring also displays an envelope conformation with a methylene C atom as the flap. In the crystal, O-HN hydrogen bonds between hydroxy groups and pyridine rings link inversion-related molecules into dimers. Weak C-HO hydrogen bonds further link the dimers into supramolecular chains running along the c axis.
