Potassium phthalimide (4.90 mg, 26.4 mmol), sodium iodide (495 mg, 3.30 mmol), and DMF (22 mL) were added to 1-(4-chlorobutyl)-2-methyl-2H-pyrazolo[3,4-c]quinolin-4-amine (4.00 g, 13.2 mmol, prepared as described in Parts A-F of Examples 454-489), and the reaction was heated at 90° C. for two hours under a nitrogen atmosphere and allowed to cool to ambient temperature. Water (100 mL) was added and a precipitate formed and was isolated by filtration to yield 3.7 g of 2-[4-(4-amino-2-methyl-2H-pyrazolo[3,4-c]quinolin-1-yl)butyl]-1H-isoindole-1,3(2H)-dione that was used in the next step.
