Reaktionsschritte

Lithium aluminum hydride (10.4 mL, 1M in THF, 10.4 mmol) was added to a solution of 5-trifluoromethoxyisatin (0.8 g, 3.45 mmol) in THF at room temperature and the mixture was refluxed overnight. The reaction mixture was cooled, and Na2SO4 10H2O was added very carefully portionwise, followed by ethyl acetate. The reaction mixture was then filtered, and the filtrate was evaporated. The residual oil was purifed by column chromatography with ethyl acetate in hexanes (2:98) to yield 5-trifluoromethoxy-1H-indole (0.162 g, 23%).
