[3-(2-Acetylamino-ethyl)-1H-indol-5-yl]-carbamic acid allyl ester (1 mmol) is dissolved in THF (27 mL) and borane-THF (2 mmol) added dropwise. After 2 h, sodium hydroxide (4 mL of 3 M) and hydrogen peroxide (4 mL of 30%) are added and the solution stirred an additional 1 h. The solution is concentrated to half its volume, 10 mL water is added and it is extracted with ethyl acetate (4×25 mL).
