Procedure

7.4 g (50 mmol) of 2.1.3-benzoxadiazole-4-aldehyde, 10 g (0.1 mol) of nitroacetone and 15.6 g (50 mmol) of 3-aminocrotonic acid 4-(3-trifluoromethylphenyl)piperazide are heated in isopropanol at 60° C. for 6 hours. The product crystallizes after part of the solvent has been evaporated off, and is recrystallized from a little isopropanol.
