A solution of potassium hydroxide in methanol (5% w/v, 17 mL) containing 5-isopropyl-1-trifluoroacetylindole (Example 2a, 1.163 g, 4.55 mmol) was stirred at room temperature overnight. After removal of the methanol, the product was partitioned between ethyl acetate and water, washed sequentially with water and brine, and dried over sodium sulfate. Flash chromatography (silica, 10% ethyl acetate in hexanes) yielded 5-isopropyl-1H-indole (715 mg, 98%).
