実験手順
This compounds was synthesised in the same manner as described above. 4-Chlororesorcinol (0.125 g, 0.87 mmol), [2-(3-Cyano-propoxy)-phenyl]-acetic acid (0.19 g, 0.87 mmol), BF3Et2O (5 ml), PCl5 (0.27 g, 1.3 mmol), DMF (8 ml and 5 ml). Crude 4-[2-(6-Chloro-7-hydroxy-4-oxo-4H-chromen-3-yl)-phenoxy]-butyronitrile was obtained as an oil which was taken onto the next stage without further purification.
