실험 절차

This compound was prepared using 2-[(pyridin-3-yl)hydrazono]malononitrile (342 mg, 2 mmole), which was derived from 3-aminopyridine (940 mg, 10 mmole)) and malononitrile (858 mg, 13 mmol) as described in Example 8, and hydrazine hydrate (110 mg, 2.2 mmole) in ethanol. Solids had not formed after heating the reaction at 80° C. for 40 minutes, however, analysis of the reaction solution by TLC indicated that no starting material remained. The solution was allowed to cool to room temperature and the solvent was evaporated. The product was obtained after upon re-crystallization from ethanol as a yellow solid (150 mg). 1H NMR (ppm, DMSO-d6): 6.18 (br., s, 4H), 7.20 (dd, 1H), 8.00 (dd, 1H), 8.38 (d, 1H), 8.85 (s, 1H), 10.77 (br., s, 1H).
