Procedure

4-(6-fluoro-3-oxo-1,3-dihydro-2H-pyrazolo[4,3-c]cinnolin-2-yl)benzoyl chloride (100 mg, 0.29 mmol) was dissolved in anhydrous DMA (2 ml). Diisopropylethylamine (75 mg, 101 μl, 0.58 mmol) was added followed by 1-(4-aminobutyl)pyrrolidine (41 mg). The mixture was stirred at room temperature overnight. Water (5 ml) and n-butanol (5 ml) were added. The phases were separated. The organic phase was washed with water (2×5 ml). The volatiles were removed under vacuum. The product was isolated as a brown powder (50 mg, 0.11 mmol, 37%). LCMS: m/z [M+H]+ 463.
