Versuchsvorschrift

A mixture of 2-[4-(4-amino-2-propyl-2H-pyrazolo[3,4-c]quinolin-1-yl)butyl]-1H-isoindole-1,3 (2H)-dione (7.21 g, 16.9 mmol) and hydrazine hydrate (4.22 g, 84.3 mmol) in ethanol (400 mL) was heated at reflux for 2 hours. The resulting solution was allowed to cool to room temperature, filtered, and concentrated under reduced pressure to yield 3.52 g of 1-(4-aminobutyl)-2-propyl-2H-pyrazolo[3,4-c]quinolin-4-amine as a yellow solid, mp 137-139° C.
