Abstract
2,2,2-Trifluoro- and trichloroethyl imidates, which are easily prepared by reaction of a nitrile and a trihaloethanol in the presence of HCl, have proven to be excellent reagents for the preparation of amidines under mild reaction conditions. Depending on the nature of the amine nucleophile, the imidates can react either as the free-base or the hydrochloride salt in a telescoped process. In several cases, the p-bromobenzoate salt of the desired product was directly isolated from the reaction mixture.
