実験手順

A mixture of 1.00 g (3.94 mmol) of ethyl 4-chloro-7-hydroxy-1-methyl-2-indolecarboxylate, 0.56 g (3.94 mmol) of 1-fluoro-4-nitrobenzene, 0.16 g (3.94 mmol) of 60% sodium hydride and 30 ml of dimethylformamide was stirred at room temperature for 5 hours. The reaction mixture was poured onto ice water. The mixture was then extracted with ethyl acetate. After washing with water, the extract was dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure. The resulting residue was purified by silica gel column chromatography to give 1.25 g of ethyl 4-chloro-1-methyl-7-(4-nitrophenoxy)-2-indolecarboxylate.
