Versuchsvorschrift

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and reflux condenser was charged with 217a (158 mg, 0.30 mmol), 1H-imidazo[4,5-b]pyridin-5-amine (80 mg, 0.60 mmol), Pd2(dba)3 (27 mg, 0.030 mmol), XantPhos (35 mg, 0.061 mmol), cesium carbonate (200 mg, 0.60 mmol), and 1,4-dioxane (5 mL). After three cycles of vacuum/argon flush, the mixture was stirred at 100° C. for 6 h. After this time the reaction was cooled to room temperature. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica-gel column chromatography eluting with 30:1 dichloromethane/methanol to afford 217b (40 mg, 23%) as a yellow solid. MS-ESI: [M+H]+ 579.4
