実験手順

A mixture of 1-(4-chlorobutyl)-2-ethyl-2H-pyrazolo[3,4-c]quinoline-4-amine (prepared as described in Example 19, 1.0 g, 3.3 mmol), 1-(2-pyridyl)piperazine (0.752 mL, 4.95 mmol), potassium carbonate (1.8 g, 13.2 mmol), and sodium iodide (123 mg, 0.825 mmol) in DMF (6 mL) was heated at 60° C. for 1 hour, then at 90° C. for 2 hours. The reaction was allowed to cool to ambient temperature and white solid formed. Water (100 mL) was added to the mixture. The mixture was stirred for 30 min and the solid was isolated by filtration and dried to yield 1.4 g of 2-ethyl-1-[4-(4-pyridin-2-ylpiperazin-1-yl)butyl]-2H-pyrazolo[3,4-c]quinolin-4-amine monohydrate as a white solid, mp 183-184° C.
