Start with a benzene ring. 
 
1. At carbon-1, attach a carboxylic acid group (-COOH).  
2. At carbon-3 (meta to the acid group), attach the nitrogen of a pyrrole ring (five-membered aromatic ring with one nitrogen).

From the pyrrole ring, at the carbon adjacent to the pyrrole nitrogen, extend a side chain:

- This carbon is bonded to an sp2 carbon.
- The sp2 carbon is double-bonded (E configuration) to a nitrogen atom (N1).
- N1 is single-bonded to a second nitrogen atom (N2).
- N2 is double-bonded to a carbon atom that bears two substituents:
    (1) A hydroxyl group (-OH).
    (2) A methylene group (-CH2-) linked to an aromatic ether: -O-(4-bromophenyl), where the bromine atom is para to the oxygen substituent on the phenyl ring.

No additional stereocenters are present.
