Reaction Steps

A mixture of 4-(5,8-Dinitro-1,3-dioxo-1H,3H-benzo[de]isoquinolin-2-yl)-butyric acid (see example 4; 0.37 g, 1 mmol), palladium on charcoal 10% and dimethylformamide (20 mL) was hydrogenated at room temperature with vigorous stirring for 24 hours. The catalyst was filtered off and the filtrate evaporated under reduced pressure. The residue was crystallized from dimethylformamide and water to give the desired product.
