Start with a benzene ring numbered to have substituents at carbon 1 and at the para position (carbon 4).

- At carbon 1, attach a tertiary amide group (-C(=O)-N-) in which the carbonyl carbon is directly bonded to the benzene ring. The amide nitrogen is substituted with:
  (1) a methyl group, and
  (2) a two-methylene chain linker (-CH2-CH2-) connecting to a tertiary amine bearing two ethyl groups (-CH2-CH3), and the whole substituent is: -C-C-N(-C-C)-C-C.

- At carbon 4, attach an ortho-methyl para-cyanophenyl group. In this case, a second benzene ring is connected such that it has a methyl substituent at the ortho position relative to the point of attachment and a cyano group (a carbon atom is triple-bonded to a nitrogen atom) at the para position.
