Start with a saturated six-membered heterocycle arranged, in sequence, N1-C2-C3-O4-C5-C6 (all ring bonds single; morpholine-like). At C2, doubly-bond to an oxygen (C2=O). The ring nitrogen (N1) is substituted with a 3-bromophenyl group (bromine meta to the attachment point). At C3, attach an N-methylamino substituent linked via a methylene, -CH2-NH-CH3.

No additional substituents or stereochemical features are specified.
