Participants

Conditions

Temperature: 50 °C

Procedure

1H-Benzoimidazol-5-ylamine (1 mmol) and Benzo[1,2,5]oxadiazole-5-carbaldehyde (1 mmol) were added to ethanol (5 ml). After 30 min 4-Cyclopropyl-2,4-dioxo-butyric acid ethyl ester (1 mmol) was added. The reaction was heated to 50° C. and stirred for 24 h. After evaporation of the solvent the residue was purified with chromatographic methods.
