Reaction Steps
To a solution of 2-bromo-4-fluorobenzaldehyde (300 mg, 1.48 mmol) in 3.0 mL of N,N-dimethylformamide was added potassium carbonate (204 mg, 1.48 mmol), piperidine (154 μL, 1.55 mmol) at room temperature. After being stirred at 110° C. overnight, the reaction mixture was diluted with a 2:1 solution of ethyl acetate and hexane. The solution was washed with water, brine, and dried over MgSO4. After filtration, the filtrate was concentrated in vacuo, and the residue was purified by silica gel column chromatography (hexane/ethyl acetate=100/0 to 75/25) to obtain the title compound (355 mg, 90%).
