lfuran-2-carboxylic acids with triethylphosphite yields the corresponding phosphonates. These compounds are brominated with N -bromosuccinimide in carbon tetrachloride at the α-position of the alkyl radical. The resulting 2-(1-bromoethyl)-, 2-(1-bromopropyl)-, and 2-(1-bromoisobutyl)furans react with secondary amines following the scheme of nucleophilicsubstitution. The dehydrobromination product
