The core skeleton is a fused bicyclic system composed of a piperazine ring and a morpholine ring.

- The piperazine is a six-membered saturated heterocycle with two nitrogens in para positions.
- The morpholine is another six-membered saturated heterocycle containing one nitrogen and one oxygen in para positions.
- The fusion occurs such that the two rings share one nitrogen atom and the carbon adjacent to that nitrogen.

Within this fused framework, attention is given to a morpholine carbon adjacent to the oxygen. Of the two carbons that meet this description, the one chosen is further from the piperazine nitrogen that is not part of the fusion. This carbon is a chiral center, assigned the R configuration.

This R-configured carbon is directly bonded to a benzene ring.

On this benzene ring:
- The point of attachment is defined as C1.
- C2 and C4 (ortho and para to C1) each carry a fluorine substituent.
- C3 (meta to C1) carries a cyano group (-C#N, a carbon triple bonds to a nitrogen).
