Reaktionsschritte
To an N,N-dimethylformamide (50 mL) solution of 2,6-difluoropyridine (5 g, 43.4 mmol) and 4-(hydroxymethyl)benzonitrile (8.67 g, 65.1 mmol) was added sodium hydride (2.56 g, 65.1 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 NH-silica gel column chromatography (heptane:ethyl acetate=10:1-4:1) to obtain the title compound (5.99 g, 61%).
