Versuchsvorschrift

4-(2-hydroxyethyl)-pyridine is oxidized to 4-(2-hydroxyethyl)-pyridine-N-oxide which is in turn treated with trimethylsilyl cyanide to yield 4-(2-hydroxyethyl)-2-cyanopyridine which is converted to ethyl 4-(2-hydroxyethyl)-2-pyridine carboxylate and then hydrogenated to yield ethyl 4-(2-hydroxyethyl)-piperidine-2-carboxylate.
