1. Begin with a benzene ring ("Ring A") that has a single substituent at one of its carbon (designated as A1).
2. The substituent at A1 is a carbon (C1) with three additional connections:
  - An unsubstituted phenyl ring ("Ring B").
  - A single bond to an imine nitrogen (N1).
  - A bond to a hydrogen, completing C1's valency.
3. N1 is double-bonded to a carbon (C2), which also carries a hydroxyl group (OH) and is single-bonded to another carbon (C3).
4. C3 has a methyl substituent and is also bonded to a sulfur atom (S1).
5. S1 is connected to a six-membered aromatic ring containing one nitrogen ("Ring C"). In Ring C, the sulfur is attached to the ring carbon designated as C1', while the ring nitrogen is positioned at N6'. A sulfonyl group (-S(=O)2-) is attached at C4' (meta to N6').
6. The sulfonyl group is also bonded to a nitrogen that is a part of a six-membered piperidine ring ("Ring D").
7. Rings A, B, C, and D have no other substituents. There is no stereochemistry (no chiral centers or E/Z sites) to specify.
