実験手順
A mixture of 6-chloromethyl-2-pyridinecarbonitrile (2.75 g) and potassium phthalimide (3.35 g) in N,N-dimethylformamide (27.5 ml) was stirred at ambient temperature for 4 hours. After the solvent was evaporated in vacuo, water (50 ml) was added to the residue and the resulting precipitate was collected by filtration to give 6-phthalimidomethyl-2-pyridinecarbonitrile (4.60 g).
