实验步骤: A mixture of the 2-trimethylsilyl indole product of Example 1 (0.50 g, 2.6 mmol) in 5 mL methanol was treated with 2.5N HCl (2.11 mL, 5.2 mmol) and the reaction mixture was aged at room temperature for 2 h. Isopropyl acetate (50 mL) and water (10 mL). were then added. The layers were separated and the organic layer was concentrated under vacuum. The residual oil was chromatographed over silica gel to afford the indole as a white solid. were then added The layers were separated the organic layer was concentrated under vacuum The residual oil was chromatographed over silica gel

实验步骤: Preparation of 2-trimethylsilyl indole ##STR15## A mixture of iodoaniline (2.19 g, 10 mmol), acyl silane (2.36 g, 20 mmol, prepared according to the procedures of reference example A), DABCO (1,4-diazabicyclo[2.2.2]octane, 3.36 g, 30 mmol) and Pd(OAC)2 (112.25 mg, 0.5 mmol) in 30 mL DMF was degassed via N2 /vacuum and heated at 105° C. for 36 h. The mixture was cooled to room temperature, diluted with IPAc (isopropyl acetate, 100 mL) and washed with 2×50 mL of water. The IPAc layer was concentrated in vacuum and chromatographed over silica gel to give 2-trimethylsilyl indole and indole. prepared was degassed via N2 /vacuum The mixture was cooled to room temperature diluted with IPAc (isopropyl acetate, 100 mL) washed with 2×50 mL of water The IPAc layer was concentrated in vacuum chromatographed over silica gel
