Versuchsvorschrift

A stirred solution of 6′-bromo-1′-(7-fluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-yl)-1′,2,2′,3,5,6-hexahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridine] (25 mg, 0.049 mmol), 4,4,5,5-tetramethyl-2-(1H-pyrazol-4-yl)-1,3,2-dioxaborolane (9.60 mg, 0.049 mmol), PdCl2(PPh3)2 (3.5 mg, 4.95 μmol) and Na2CO3 (10.5 mg, 0.099 mmol) in toluene:water (2 mL:1 mL) was heated in the microwave for 2 h at 120° C. After this time PdCl2(PPh3)2 (5.0 mg) and 4,4,5,5-tetramethyl-2-(1H-pyrazol-4-yl)-1,3,2-dioxaborolane (9.60 mg, 0.049 mmol) was added and the reaction was heated in the microwave for 1 h at 140° C. After this time the reaction was partitioned between EtOAc (50 mL) and water (20 mL). The separated organic layer was dried with MgSO4, filtered and evaporated in vacuo. Reverse phase HPLC (10 to 60% acetonitrile:water) gave 1′-(7-fluoro-3-methyl-2-(2-pyridinyl)-4-quinolinyl)-6′-(1H-pyrazol-4-yl)-1′,2,2′,3,5,6-hexahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridine]. Mass Spectrum (ESI) m/e=493.0 (M+1).
