Abstract: The invention relates to a one-pot reaction for the production of 3,7-diaza-bicyclo[3.3.1]nonane compounds, wherein in a first step a dicarboxylic acid ester is reacted with a pyridine aldehyde and a primary amine. The piperidone created in this manner is reacted with formaldehyde and a further primary amine in a second step. It is essential to the invention that both reaction steps are carried out in a one-pot variation in a C1-C4 alcohol as the solvent, and that the reaction water created is removed by means of distillation.

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.
