Begin with a benzene ring bearing two substituents:
- At ring position 1, attach a sulfonamide group. In this group, the sulfonyl sulfur is double-bonded to two oxygens and is further single-bonded to a nitrogen atom (which is part of the piperidine ring described below).
- At ring position 2, attach a methyl group.

The sulfonamide nitrogen is part of a piperidine ring. Adjacent to this nitrogen on the piperidine ring is a chiral carbon (R configuration) that carries a five-membered ring substituent. This five-membered ring is composed of one nitrogen, one sulfur, and three carbons, arranged as C1-S2-C3-C4-N5. In this five-membered ring, C1 is bonded to the piperidine, while C1 is double-bonded to N5 and C3 is double-bonded to C4.
