Begin with a benzene ring. At one of its carbons (designated position 1), attach a carbonyl-N group to form an amide. This nitrogen is incorporated into a piperazine ring, a saturated six-membered ring containing two nitrogen atoms at opposite positions. On the second nitrogen of the piperazine, introduce a single methylene linker leading to a five-membered aromatic heterocycle that contains one nitrogen and one oxygen atom. Number this heterocycle in a counterclockwise direction, so that the ring nitrogen is at position 1 and the oxygen is at position 3. The methylene linker is attached at position 5, and the carbon located between the nitrogen and oxygen bears a benzene ring substituted with two fluorine atoms, both positioned at the ortho positions relative to the attachment point (i.e., forming a 1,3-difluorobenzene substituent).
