실험 절차

A suspension of vanillin (1.0 g, 6.57 mmol), 2-(6-(trifluoromethyl)pyridin-3-yl)acetonitrile (1.222 g, 6.57 mmol) and piperidine (0.71 mL, 7.23 mmol) in absolute ethanol (10 mL) was stirred at reflux for forty-eight hours and then allowed to cool to room temperature. The resulting precipitate was filtered off, washed with water and dried. Recrystallisation from isopropanol afforded (Z)-3-(4-hydroxy-3-methoxyphenyl)-2-(6-(trifluoromethyl)pyridin-3-yl)acrylonitrile as white crystals, 0.904 g (43%).
