实验步骤: A mixture of 4-bromo-1H-pyrazole (400 mg, 2.72 mmol), 4-(chloromethyl)benzamide (462 mg, 2.72 mmol), and potassium carbonate (940 mg, 6.80 mmol) in DMF (5 mL) was stirred for 2 hours at 80° C. The reaction mixture was then cooled to ambient temperature and diluted with diethyl ether (400 mL). The mixture was washed with water (2×100 mL) and brine (25 mL). The organic layer was dried over magnesium sulfate, filtered, and concentrated under reduced pressure to afford the crude product residue. The crude product residue was suspended in ethyl acetate (10 mL) and then diluted by the drop wise addition of n-heptane (40 mL). After stirring for 18 hours, the mixture was filtered and the collected solids were washed with n-heptane (3×10 mL). The collected solids were dried under reduced pressure to afford 4-((4-bromo-1H-pyrazol-1-yl)methyl)benzamide.
