1. Begin with a three-carbon chain. Label these C1-C3 from left to right.
    - C1 is a simple methyl group (-CH3).
    - C2 bears a single-bonded oxygen that connects to a benzene ring. On that benzene ring, the oxygen is attached at ring position 1, and a methoxy (-OCH3) substituent is present position 2 (i.e., ortho to the bridging oxygen).
    - C3 is bonded to a nitrogen atom (call it N4).
2. N4 is part of an amidoxime-like linkage : N4 is double-bonded to a carbon (C5) that is single-bonded to a hydroxyl (-OH). Additionally, C5 is bonded to another nitrogen (N6).
3. N6 is bonded to a carbon (C7), which bears a methyl substituent and is also attached a five-membered aromatic heterocycle (an oxazole, referred to as Ring B).
4. Ring B has the following sequence around it:
    - R1 is an oxygen atom.
    - The point of attachment to C7 is at ring carbon R2.
    - R3 is a nitrogen.
    - R4 is a carbon.
    - R5 is a carbon that carries an unsubstituted phenyl ring as a substituent.
