A benzene ring serves as the core.  
1. Number the ring so that carbon-1 bears fluorine.  
2. At C-2 (ortho to fluorine) there is a five-atom side chain with the following sequence:
   - A methylene group (-CH2-) directly attached to the ring.
   - This methylene is bonded to a carbon that bears a single methyl substituent and is further connected to a secondary amine nitrogen (-NH-).
   - The amine nitrogen is bonded to another methylene group (-CH2-).
   - Finally, this methylene is attached to a tertiary carbon substituted with a hydroxyl group (-OH) and two methyl groups.
