Start with an sp2 carbon (C-1).  
Attachments to C-1:  
1. A hydroxyl group (-OH).  
2. A methylene group (-CH-, denoted as C-2).  C-2 is bonded to an oxygen that is in turn bonded to the 1-position of a benzene ring.  
   - On that benzene ring, place chlorine atoms at the 2- and 4-positions relative to the O-substituted carbon.  
3. A double bond to an imino nitrogen N-1 (C-1=N-1).  

Further substitution on N-1:  
N-1 is single-bonded to a second nitrogen N-2.  
N-2 is tertiary, bearing two methyl groups.

No stereochemical information is specified for the C=N bond (draw as unspecified E/Z).
