Abstract: The invention relates to a method for producing the compositions cited in the title. According to this method: dipyridyl ketone is reacted with hydroxylamine; the oxime obtained thereby is reduced without intermediate isolation to form 1,1-di-(2-pyridyl)-methylamine, and; this amine is firstly reacted with 1 to 1.5 molar equivalent of picolyl chloride and then with another 1 to 1.5 molar equivalent of picolyl chloride to form the amine of formula (1). This amine is purified via the tetrafluoroborate salt and subsequently alkylated with an alkyl iodide. This method represents an improvement with regard to prior art methods for producing these compounds.
