Versuchsvorschrift
A mixture of 3-hydroxychromone (4.86 g, 0.03 mole), chloroacetonitrile (2.26 g, 0.03 mole) and potassium carbonate (3.0 g, 0.02 mole) in dimethylformamide (40 ml) is stirred at 100° C. under nitrogen for 4 hrs. The reaction mixture is cooled, poured into water (200 ml), filtered, washed with water and sucked dry. Recrystallization from methanol gives white crystals (4.7 g, 94%), mp 145°-146° C.
