Versuchsvorschrift

Potassium acetate (0.83 g, 8.432 mmol) and sodium iodide (16 g, 1.05 mmol) was added to a solution of di(tert-butyl) 1-(4-chlorobutyl)-2-propyl-2H-pyrazolo[3,4-c]quinolin-4-ylimidodicarbonate (2.18 g, 4.22 mmol) in DMF (15 mL). The reaction mixture was heated at 90° C. under a nitrogen atmosphere for 4.5 hours. The reaction was allowed to cool to ambient temperature and the volatiles were removed under reduced pressure. The resulting oil was partitioned between ethyl acetate and water. The organic layer was isolated and washed with water (2×25 mL) and brine (3×20 mL), dried over magnesium sulfate, filtered, and concentrated under reduced pressure to yield an oil that was dried under vacuum to provide 1.76 g of 4-{4-[bis(tert-butoxycarbonyl)amino]-2-propyl-2H-pyrazolo[3,4-c]quinolin-1-yl}butyl acetate.
