A saturated five-membered ring containing one nitrogen (pyrrolidine).  Number the ring with the nitrogen as position 1, then clockwise to C-2, C-3, C-4 and C-5.

Substituents  
1. On the nitrogen (position 1): attach a carbonyl (-C(=O)-) whose carbonyl carbon is bonded to a phenyl ring.  The phenyl carries a bromine at the position meta to the carbonyl (i.e. it is a 3-bromobenzoyl group).  
2. On C-2 of the pyrrolidine: attach a pyridine ring through its 2-position (the carbon alpha to the ring nitrogen).  Place a methyl group on the pyridine carbon that is ortho to the ring nitrogen on the side opposite the point of attachment (the 6-position).
