Reaktionsschritte

A solution of 1,3-cyclohexanedione(0.11 g, 1 mmol), 3,4-dibromobenzaldehyde(0.26 g, 1 mmol), and 3-aminopyrazole(0.11 g, 1.27 mmol) in ethanol (10 mL) was heated at 80 ° C. in a sealed 20 mL vial for 3 days. After the reaction mixture was allowed to cool to ambient temperature, the resulting solid was isolated by filtration and recrystallization from acetone to provide 0.23 g (56%) of the title compound.
