The core is an aromatic furan ring (five-membered ring with one oxygen atom).

Substituents at the two carbons adjacent to the furan oxygen:
- First adjacent carbon: bonded to a phenyl ring. On this phenyl substituent, the meta position relative to the furan attachment carries a chlorine atom, and the para position carries a fluorine atom.
- Second adjacent carbon: bonded to a methylene group (-CH2-). This methylene connects to a secondary amine nitrogen (-NH-). The nitrogen is further extended by a two-methylene spacer (-CH2-CH2-) terminating in a methoxy group (-OCH3).
