Williamson ether synthesis it may be that the nh2 on the amide needs a protecting group it might be possible to use a nitrile (start from bromoacetonitrile) as a masked form of the amide and then gently hydrolyse the nitrile to the amide at the end. This reaction is called the williamson ether synthesis it involves treatment of a parent alcohol with a strong base to form the alkoxide, . Williamson method the williamson ether synthesis proceeds via an s n 2 mechanism, in which an alkoxide ion displaces a halogen ion this method cannot be used with tertiary alkyl halides, because the competing elimination reaction predominates.
