Synthesis and pharmacological activity of derivatives of exo-trimethylenenorbornane. III.

Two synthetic routes to (exo-5,6-trimethylenenorbornan-2-ylidene)acetonitrile starting from exo-5,6-trimethylenenorbornan-2-one are described. From the above-mentioned nitrile, 2-(exo-5,6-trimethylenenorbornan-2-ylidene)ethanamine and 2-(exo-5,6-trimethylenenorbornan-2-yl)ethanamine, as well as N,N-dimethyl and N,N-diethyl derivatives of the latter, were prepared.
