Procedure
150 mg (0.857 mmol) of 2,4-dichlorobenzaldehyde, 133 mg (0.857 mmol) of the compound from example 4A and 70 mg (0.857 mmol) of 3-aminocrotononitrile are dissolved in 4 ml of isopropanol and stirred at the reflux temperature overnight. After cooling to room temperature, the volatile components are removed in a rotary evaporator, and the crude product is taken up in 3 ml of ethyl acetate. The crystallizing solid is removed by filtration. The product obtained in this way is washed with a little diethyl ether. 85 mg (26% of theory) of the title compound are obtained.
