The molecule is built on benzene ring A, which carries two substituents in the ortho position. One is a simple methyl group, while the other is an extended nitrogen-containing side chain.
   - The side chain begins with a benzylic methylene (-CH2-) directly attached to the aromatic ring.
   - This methylene links to a secondary amine nitrogen (N1).
   - N1 is single-bonded to an sp2 carbon (C-alpha) that constitutes the central carbon with three nitrogens bonded including N1.
   - N1 is connected to an sp2 carbon (C-alpha), which serves as a hub for three nitrogen attachments:
       1. the original N1,
       2. an imine nitrogen (N2) double-bonded to C-alpha and bearing an ethyl group (-CH2-CH3),
       3. and a second sp2 nitrogen (N3) single-bonded to C-alpha.
   - N3 continues the chain through a methylene (-CH2-), which then joins a second aromatic ring (benzene ring B).
   - On ring B, a cyano group (-C#N) is located para to the methylene attachment point.

No stereocenters or E/Z issues are present.
