반응 단계

To an N,N-dimethylformamide (15 mL) solution of 2-chloro-4-fluoropyridine (2.88 g, 21.9 mmol) and 4-(hydroxymethyl)benzonitrile (4.37 g, 32.9 mmol) was added sodium hydride (1.29 g, 32.9 mmol, 60% in oil) at room temperature. This mixture was stirred for 4 hours at 70° C. This mixture was partitioned into ethyl acetate and water. The organic layer was separated, washed with water, dried over anhydrous magnesium sulfate, and filtered. The filtrate was concentrated under a reduced pressure, and the residue was purified by silica gel column chromatography (heptane:ethyl acetate=4:1-2:1) to obtain the title compound (4.08 g, 82%).
