Reaction Steps

4-(2-Bromoethyl)-1-piperidinecarboxaldehyde (47 g, 0.213M) and NaCN (24 g) in ethanol (470 ml) was refluxed for 4 hours. Solvent was removed, added water (30 ml) and extracted with methylene chloride (4×200 ml). The extracts, dried over NaSO4, were stripped to dryness and then purified on silica gel columns eluted with ethyl acetate to give 4-(2-cyanoethyl-1-piperidinecarboxaldehyde (16 g, 50% yield).
