Versuchsvorschrift

A suspension of tert-butyl 4-(6-(6-chloro-1H-pyrazolo[4,3-c]pyridin-1-yl)Pyridine-2-yl)-6-hydroxy-1,4-diazepane-1-carboxylate (160 mg, 0.36 mmol), 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (140 mg, 0.72 mmo), Pd(dppf)Cl2 (147 mg, 0.18 mmol), and aq. Na2CO3 (2.0 M, 1 mL) in 1,4-dioxane (10 mL) under nitrogen was heated at 100° C. for 16 hours. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel chromatography using EtOAc as eluting solvent to afford tert-butyl 4-(6-(6-(1H-pyrazol-4-yl)-1H-pyrazolo[4,3-c]pyridin-1-yl)pyridin-2-yl)-6-hydroxy-1,4-diazepane-1-carboxylate as a yellow solid (60 mg, 35%). MS (ESI) m/z: 477 [M+H]+.
