Versuchsvorschrift

A suspension of 4-(6-(6-(1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)-1,4-diazepane-1-carboxylate (200 mg, 0.43 mmol), (bromomethyl)cyclopropane (100 mg, 0.65 mmol), and K2CO3 (120 mg, 0.87 mmol) in DMF (10 mL) was stirred at room temperature for 18 hours. The reaction mixture was extracted with EtOAc (100 mL), washed with brine (50 mL), dried over MgSO4, and concentrated under reduced pressure. The crude was purified by silica gel chromatography using petroleum ether/EtOAc (2/1) as eluting solvents to afford tert-butyl 4-(6-(6-(1-(cyclopropylmethyl)-1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)-1,4-diazepane-1-carboxylate as a white solid (200 mg, 89.6%). MS (ESI) m/z: 515 [M+H]+.
