Reaktionsschritte
1-cyanomethyl-1-(2-picolyl)pyrrolidinium benzenesulfonate (see Preparation II) is rearranged and alkylated with 3-bromopropionitrile as in Example 2. The resulting dicyanoamine is decyanated with sodium borohydride in ethanol to give the product. Purification is effected via the picrate.
