Procedure

Add ethanolamine (5 mL, 82 mmol) to a solution of 7-(2-(methanesulfonyloxy)eth-1-yl)indole (0.79 g, 3.3 mmol) in ethanol (50 mL) and stir the reaction mixture at reflux overnight. Dilute with ethyl acetate (150 mL), wash sequentially with water (3×50 mL) and saturated aqueous sodium chloride (2×50 mL), dry over sodium sulfate, filter, and concentrate under reduced pressure to provide 7-(2-(N-[2-hydroxyeth-1-yl]amino)eth-1-yl)indole as a light-brown solid (0.57 g, 85%).
