Reaction Steps

3-Cyano-8-methyl-8-azabicyclo[3.2.1]octane (IV) can be prepared by treating tropinone (V) with tosylmethyl isocyanide in the presence of a suitable base, such as potassium ethoxide. Alternatively, 3-cyano-8-methyl-8-azabicyclo[3.2.1]octane (IV) can be prepared by treating tropine (X) with thionyl chloride to give 3-chloro-8-methyl-8-azabicyclo[3.2.1]octane (XII) and reacting (XII) with cyanide as described in J. Am. Chem. Soc., (1958) 80, 4677.
