Procedure
Following a method similar to 3-morpholin-4-yl-1H-indole using 3-Piperidin-1-yl-1-triisopropylsilanyl-1H-indole (0.30 g, 0.84 mmol) and 1N solution of tetrabutylammonium fluoride (1.30 mL). Purify by flash chromatography using 20 to 50% of EtOAc in hexanes to give the title compound (0.12 g 71%). MS (ES) 201.1 (M+1)+.
