Dear friends, I have synthesis problems and require some help from you. I have a compound in this form (NH2)-Ar-CH2CHCl-R. I wish to start a condensation reaction between the NH2 group and an aldehyde group but am worried that if the secondary alkyl halide would also react with the amine group simultaneously. My question is, would the above mentioned competition take place under a reflux condition in a purely organic solvent? if yes, do I have any way to prevent it. Hope to get some idea from all of you out htere. Thanks in advance and regards, Barnabas ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com __________________ ORGLIST - Organic Chemistry Mailing List WWW Homepage and Archive: http://www.orglist.net/ List coordinator: Joao Aires de Sousa (jas@mail.fct.unl.pt)
