Versuchsvorschrift

tert-butyl 3-(3-bromo-1-trityl-1H-indazole-5-carboxamido)-4-(3-fluorophenyl)-piperidine-1-carboxylate (80 mg, 0.105 mmol) was added to a vial containing pyridin-4-ylboronic acid (13 mg, 0.105 mmol) and tetrakis(triphenylphosphine)palladium (13 mg, 0.0105 mmol). After purging the vial with nitrogen gas, dioxane (0.5 mL) and 2M sodium carbonate (0.5 mL) was added to the vial respectively. The reaction mixture was stirred and was heated to 80° C. for overnight. Upon completion, the mixture was concentrated under vacuo. Water (3 mL) was added and was extracted using dichloromethane (3×5 mL). The extracts were combined and dried using anhydrous sodium sulfate. The resulting suspension was filtered and concentrated. The crude product was progressed to the next step without purification.
