Begin by envisioning a five-membered aromatic ring that contains two adjacent nitrogen atoms and three carbon atoms (i.e., a pyrazole ring). Number the ring atoms in a clockwise direction as N1, N2, C3, C4, and C5. The substituents on each atom are as follows:
1. N1 is linked to an n-propyl group (-CH2-CH3-CH3).
2. N2 bears no additional substituents.
3. C3 is attached to a hydrogen atom.
4. C4 is bonded to a carbon atom that is connected both to a hydroxyl group and, via an imine linkage (C=N), to a nitrogen. This imine nitrogen is connected through a methylene group (-CH2-) to a cyclohexane ring (six carbon saturated ring). Designate the attachment point on the cyclohexane as C-alpha; the adjacent cyclohexane carbon (C-beta) carries a hydroxyl substituent, rendering both C-alpha and C-beta chiral with S configuration. The cyclohexane ring has no other substituents.
5. C5 is connected to an unsubstituted cyclopropane ring (three carbon saturated ring).
