1. Begin with a bicyclic substituent (Ring A and Ring B)
   - Ring A: labeled as A1-A2-A3-A4-A5-A6, where A1 bears a methyl group and A6 is nitrogen (N1). A1 and A2 are double-bonded; A3 and A4 are double-bonded.
   - Ring B: labeled as B1-B2-B3-B4-B5-B6. Ring A and Ring B share two atoms: B6 is equivalent to N1 (A6) and B5 is equivalent to A5. B1 is double-bonded to an oxygen, B2 is double-bonded to B3, and B4 is double-bonded to B5. B4 is a protonated nitrogen ([NH+]). Except A6 and B4, all other atoms in both rings are carbons.
   - B3 is also attached to a methylene that connects to a nitrogen (N3).
2. N3 is substituted with two groups:
   - a methyl group.
   - a benzyl group (-CH2-phenyl). In the benzyl group's phenyl ring, there are two substituents: a methoxy group at the ring carbon immediately adjacent to the benzyl attachment (i.e., at position 2) and a chlorine at position 5 relative to the benzyl linkage.
