实验步骤: A 100-mL round bottomed flask was equipped with a reflux condenser was charged with 3-methoxyazetidine hydrochloride (1.0 g, 8.09 mmol), 5-bromo-2-nitropyridine (1.97 g, 9.71 mmol), Pd2(dba)3 (370.1 mg, 0.404 mmol), Xantphos (467.6 mg, 0.809 mmol), Cs2CO3 (7.9 g, 24.3 mmol), and dioxane (50 mL). After bubbling nitrogen through the reaction mixture for 20 minutes, it was heated at 100° C. under N2 protection for 3 h. Analysis of the reaction mixture by LCMS showed complete conversion to the desired product. It was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the residue was purified by silica-gel column chromatography eluting with 50:1 dichloromethane/methanol to afford 323a as a yellow solid (1.63 g, 96%).

实验步骤: 5-Bromo-2-fluoropyridine (1.7 g) was mixed with N,N-dimethylacetamide (5 ml), and 3-methoxyazetidine hydrochloride (335 mg) and potassium carbonate (1.5 g) were added thereto, followed by stirring at 100° C. overnight. The reaction mixture was concentrated under reduced pressure, and CHCl3 and water were then added thereto. The organic layer was dried over Na2SO4 and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/EtOAc) to obtain 5-bromo-2-(3-methoxyazetidin-1-yl)pyridine (581 mg). were added The reaction mixture was concentrated under reduced pressure, and CHCl3 and water were then added The organic layer was dried over Na2SO4 concentrated under reduced pressure The obtained residue was purified by silica gel column chromatography (hexane/EtOAc)
