実験手順

To a solution of 6-nitro-1H-indole (0.5 g) in N,N-dimethylformamide (10 mL) were added cesium carbonate (1.2 g) and 4-fluoro benzoic acid ethyl ester (0.62 g), and this mixture was stirred at 75° C. overnight. This reaction mixture was poured into water and the precipitated solid was collected by filtration, and washed with water and n-hexane, dried under reduced pressure to give the title compound (0.64 g).
