1. Begin with a benzene ring bearing one substituent (designated as carbon-1 of the benzene).
2. That substituent is -CH2- attached to a six-membered piperidine ring (ring A) via the ring's nitrogen.
3. At the carbon opposite to this nitrogen (carbon-4 of ring A), there is an imine substituent: this ring carbon (C-4) is bonded to a nitrogen, which is double-bonded to a carbon atom. The double-bonded carbon also carries a hydroxyl group and a two-carbon side chain.
4. The first carbon atom of this side chain is connected to the nitrogen of another six-membered piperidine ring (ring B). The second carbon atom of the side chain (the terminal carbon) is a methyl carbon.
5. In ring B, at the position opposite the nitrogen (carbon-4 of ring B), there is an alkoxy substituent leading to a cyclohexyl ring (ring C). In other words, ring B's carbon-4 is bonded to an oxygen, which in turn is bonded to ring C (a six-membered cyclohexane).
