Begin with a bicyclic system. The first ring (Ring A) is a six-membered saturated carbocycle, numbered C1-C6, with a methoxy group attached at C1. The second ring (Ring B) is also a six-membered saturated ring that shares two carbons with Ring A (C3 and C4) and is numbered as C3-C4-N5-C6-C7-C8. At C8, the ring features a double bond to an oxygen, while C7 is bonded to the carbonyl group of an amide. The nitrogen of this amide is part of a piperazine ring, which is further substituted on its other nitrogen by a phenyl ring bearing a single fluorine at the para position.
