The molecule is centered on a tetrahedral (sp3-hybridized) carbon, which is bonded to one implicit hydrogen and three substituents:

1. A phenyl ring.  
2. A carboximidic-acid fragment: the central carbon is attached to the carbon that bears the OH and is double-bonded to a nitrogen atom.  
3. A piperidine ring (six-membered saturated ring with a nitrogen). The central carbon is attached to the ring at the position para to the nitrogen atom.

The piperidine nitrogen is acylated:
- It is bonded to a carbonyl carbon (-C=O).
- This carbonyl carbon is further connected to a carbon denoted C*.

C* carries two substituents:
- A tert-butyl group [-C(CH3)3], consisting of a central carbon attached to three methyl groups.
- An amino group (-NH2).
