Versuchsvorschrift

To a solution of 1.5 g (3.7 mmol) of ethyl 1-methyl-8-{[(trifluoromethyl)sulfonyl]oxy}-4,5-dihydro-1H-pyrazolo[4,3-h]quinazoline-3-carboxylate in 150 mL of anhydrous dioxane, 756 mg (4.1 mmol) of tert-butyl 3-aminopyrrolidine-1-carboxylate were added. The reaction mixture was stirred at room temperature overnight. The solvent was then removed under reduced pressure, the residue redissolved with dichloromethane and washed with water. The organic layer was dried over sodium sulfate and evaporated. 1.2 g (88% yield) of the title compound was collected by filtration after trituration with diethylether.
