The molecule contains three rings:
1. A benzene ring.
2. A pyrrolidine ring (a saturated five-membered ring with four carbons and one nitrogen).
3. A pyridine ring (a six-membered aromatic ring with one nitrogen).

The pyrrolidine ring serves as the central linker between the benzene and pyridine rings.
- On the benzene ring, one carbon bears a bromine atom. At the meta position relative to this bromine, the benzene ring is connected to the pyrrolidine nitrogen via a carbonyl group (-C(=O)-).
- On the pyrrolidine ring, at the ortho position relative to its nitrogen, the ring is connected to the pyridine ring through one of the carbons adjacent to the pyridine nitrogen. The other carbon adjacent to the pyridine nitrogen bears a methyl substituent (-CH3).
