Begin with a five-membered ring (N1-C2-C3-C4-C5). At N1, a chlorobenzene is attached at the ortho position. C2 is double bonded to an oxygen, forming a carbonyl group. C3 is double-bonded to C4 and also bears a hydroxyl. C4 is connected to a substituted benzene ring that features an isobutoxy group (-O-CH2-CH(CH3)CH3) at the para position. C5 is bonded to another substituted benzene ring, which carries a hydroxyl group (-OH) at the para position of the linkage and an ethoxy group (-O-CH2-CH3) at the meta position.
