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.
