Reaction Steps
To a solution of 5-bromo-3-cyanoindole (2.0 g) in N,N-dimethylformamide (50 mL) were added cesium carbonate (7.4 g) and 4-fluorobenzoic acid ethyl ester (3.0 g), and this mixture was stirred at 80° C. for 48 hours. This reaction mixture was poured into water, and the precipitated solid was collected by filtration. This solid was washed with water, dried under reduced pressure at 50° C. to give the title compound (1.8 g).
