Lithium aluminum hydride (3.38 g, 89.0 mmol) in anhydrous THF (100 mL) was cooled to −30° C. 2-[2-(Tetrahydro-pyran-2-yloxy)-ethyl]-1H-indole-5-carboxylic acid methyl ester (13.5 g, 44.5 mmol) in anhydrous THF (100 mL) was added dropwise. The reaction mixture was stirred at −20° C. for 1 hour and then at room temperature for 4 hours. The reaction mixture was cooled to 0° C. and water (6 mL) was added slowly. Ammonium chloride solution (200 mL) was added and extracted with ethyl acetate (2×200 mL). The organic phase was washed with water (100 mL), then brine (100 mL), and dried over anhydrous sodium sulfate. The solvent was evaporated to give {2-[2-(tetrahydro-pyran-2-yloxy)-ethyl]-1H-indol-5-yl}-methanol as a white solid. Yield: 11.50 g (94%).
