Hi all,
 
Am doing a regioselective reaction with  2- chlorophenol and a substituted pyridine in DMF.  It seems the phenol is not deprotonated completely in the reaction ending up with less yield. Is it possible to heat the reaction mixture? I have never done heating with NaH. Please can anyone suggest me anyother strong base for deprotonation of phenol or suggest ideas to improve yeilds?
 
Thanks, 
Thanu
