Reaction Steps
To a mixed solution of 3-fluoro-4-hydroxybenzonitrile (3.10 g) in N,N-dimethylformamide (31 ml)/water (3.1 ml) were successively added cesium carbonate (10.3 g) and sodium chlorodifluoroacetate (7.93 g). After stirring at 110° C. for 2 hr, the reaction mixture was partitioned by adding toluene and water. The aqueous layer was extracted with toluene, and the combined organic layer was washed with water. The organic layer was dried over anhydrous magnesium sulfate, filtrated, and concentrated under reduced pressure to give the title compound (4.09 g).
