1. The molecule's main framework is a pyridine ring, a six-membered aromatic ring containing one nitrogen and five carbons. Label the ring so that the nitrogen is at position 1 and the carbons are numbered 2 through 6 sequentially.
2. At carbon 2 of the pyridine ring, attach a methoxy group (-OCH3).
3. At carbon 3 of the pyridine ring, attach a fused bicyclic substituent composed of two rings (Ring B and Ring C):
   - Ring B is a 1,3-cyclohexadiene, a six-carbon ring with two double bonds. Number Ring B clockwise such that the double bonds lie between C1 and C2, and between C3 and C4. Carbon 2 of Ring B is the point of attachment to the pyridine ring, while carbons 5 and 6 serve as the bridgeheads shared with Ring C.
   - In Ring C, number the remaining atoms as follows: C7 (adjacent to C6), N8 (adjacent to C7), C9 (adjacent to N8), and C10 (adjacent to C9 and to C5). Additionally, C7 is double-bonded to an oxygen atom to form a carbonyl group, and there are double bonds between N8 and C9, as well as between C10 and C5.
