Procedure

To a solution of 7-(2-(methanesulfonyloxy)eth-1-yl)indole (0.79 g, 3.3 mmol) in ethanol (50 mL) was added ethanolamine (5 mL, 82 mmol) and the reaction stirred at reflux overnight. The reaction was diluted with ethyl acetate (150 mL) and washed with water (3×50 mL), saturated aqueous sodium chloride (2×50 mL) and dried over sodium sulfate, filtered and concentrated under reduced pressure to provide 0.57 g (85%) 7-(2-(N-[2-hydroxyeth-1-yl]amino)eth-1-yl)indole as a light-brown solid.
