1. Core amide: begin with a carbonyl carbon (C1) double-bonded to oxygen, and single-bonded both to a tertiary nitrogen (N1) and to a methylene carbon (C2).

2. Substituents on the tertiary nitrogen N1:  
   - a methyl group,  
   - a -CH2-thiophene unit, where the methylene is attached at the 3-position of an otherwise unsubstituted thiophene ring (the sulfur occupies ring position 1),  
   - the carbonyl carbon C1 of the amide described above.

3. C2: bonded to an oxygen atom, which forms an ester linkage to a second carbonyl carbon (C3).

4. C3: also bonded to a benzene ring.

5. Benzene substituent: meta to the C3 attachment, the ring carries a sulfonamide group:
   - a sulfonyl sulfur attached to the aromatic carbon, bearing two =O groups, and single-bonded to a nitrogen (N2),  
   - N2 is substituted with one methyl group and another phenyl ring, 
   - on that phenyl ring, a chlorine is meta to the point of attachment to N2 and no other substituents are present.

6. No stereocenters or defined double-bond geometry are present
