Begin with a benzene ring numbered so that:
- C1 bears a straight-chain hexyl group (a linear six-carbon chain).
- C2 bears a single methine (-CH-) substituent, which in turn carries two identical side chains. Each side chain is -NH-CH2-CH(OH)2 (i.e., an aminoethyl group bearing a geminal diol).
- C4 carries a hydroxyl group (-OH).
- C3, C5, and C6 are unsubstituted.
