Begin with a benzene ring numbered 1 through 6 in clockwise order. At positions 2, 4, and 6, attach fluorine substituents. At position 1, attach a five-member pyrrolidine ring via its nitrogen. This ring is otherwise saturated, but its third carbon (with the nitrogen counted as position 1) carries an exocyclic double bond to a carbon that bears two cyano groups, each representing a carbon atom triple-bonded to a nitrogen atom. The benzene carbons at positions 3 and 5 remain unsubstituted.
