Versuchsvorschrift
1 g (5.1 mmol) 3,4-Methylenedioxy-6-nitrobenzaldehyde, 0.4 g (6 mmol) malononitrile and 0.2 g β-alanine in 30 ml ethanol were stirred 16 hours at room temperature, 50 ml H2O was added and the reaction mixture was filtered, giving 1 g (80% yield) of a bright yellow solid, m.p. 104° C.
