実験手順
A mixture of 5-oxo-hexanenitrile (5 mL, TCI-US), 2-amino-3-formylpyridine (7 g, J. Org. Chem. 1983, vol. 48, p 3401) and ethanol (100 mL) was heated to reflux for 12 hours. Following evaporation of the solvent, the residue was chromatographed (silica gel, ethyl acetate) to give 4-[1,8]naphthyridin-2-yl-butyronitirile and the title product as colorless solids. 1H (CDCl3) δ 2.29 (3H, s); 2.83 (2H, t); 3.18 (2H, t); 7.48 (1H, dd); 8.04 (1H, s); 8.20 (1H, dd); 9.03 (1H, dd).
