Acetone → 9-(3,4-Dibromophenyl)-5,6,7,9-tetrahydropyrazolo[5,1-b]quinazolin-8(4H)-one

Participants

Reaction Steps

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.
