Start with a naphthalene ring system (two fused benzene rings). Select one of the rings and define the two adjacent carbons that are not adjacent to the ring junction as C1 and C2.

1. At C1:
   - carries a carboxamide group (-C(=O)-N-).  
   - The amide nitrogen is incorporated into a seven-membered saturated ring containing one nitrogen (an azepane ring).  
   - At the meta position relative to the nitrogen within this azepane ring, the ring carbon carries a methylthio substituent (-S-CH3).

2. At C2: 
   - bonded to a nitrogen atom.
   - This nitrogen is double-bonded to a carbon atom.
   - That carbon bears two substituents: 1) a cyclopropyl group (three-membered saturated ring), and 2) a hydroxyl group (-OH).

No stereocenters or defined double-bond geometries are present. No additional substituents occur on the naphthalene core.
