FREMGANGSMÅDE TIL FREMSTILLING AF 2,2-DIFLUORETHYLAMIN-DERIVATER VED HJÆLP AF ALKYLERING MED 2,2-DIFLUOR-1-HALOGENETHANER

摘要

Process for preparing 2,2-difluorethylamine derivatives of the general formula (III) in which A is an optionally substituted heterocycle as described in the description, by reacting a 2,2-difluoroethyl-1-haloethane compound of the general formula (I) in which Hal is Cl, Br or iodine, with an amine of the general formula (II) in which A is as defined above, optionally in the presence of a base.
