反応手順

To an N,N-dimethylformamide (50 mL) solution of 2-bromo-5-fluoropyridine (5 g, 28.4 mmol) and 4-(hydroxymethyl)-benzonitrile (5.67 g, 42.4 mmol) was added sodium hydride (1.7 g, 42.4 mmol, 60% in oil) at room temperature. The mixture was stirred for 3 hours at 70° C. The 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=4:1-2:1-1:1-ethyl acetate) to obtain the title compound (5.5 g, 85%).
