実験手順

4-(3-oxo-1,3-dihydro-2H-pyrazolo[4,3-c]cinnolin-2-yl)benzoyl chloride (97 mg, 0.30 mmol) was dissolved in anhydrous DMA (2 ml). Diisopropylethylamine (39 mg, 53 μl, 0.60 mmol) was added followed by N-cyclohexyl-1,3-propanediamine (52 mg, 0.60 mmol). The mixture was stirred for 30 min. Water (5 ml) was added to give a dark red suspension. The mixture was extracted with n-butanol (2×20 ml). The combined organic phases were washed with water and concentrated under vacuum until precipitation was observed. Hexane (20 ml) and ethyl acetate (10 ml) were added, the solids were collected by filtration and dried under vacuum. The product was isolated as a dark red powder (82 mg, 0.18 mmol, 62%). LCMS: m/z 445 [M+H]+.
