Participants

Reaction Steps

1.65 ml of a 5N aqueous potassium hydroxide solution are added to a solution of 0.18 g of 2-{5,6-dimethoxy-3-[1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl]indol-1-yl}ethanol in 10 ml of methanol, at a temperature in the region of 20° C. The reaction medium is refluxed for 4 hours. After cooling, the solid formed is filtered off through sintered glass, and washed twice with 3 ml of methanol and then five times with 5 ml of water. The solid is purified by flash-pack chromatography (silica, 95/05 by volume dichloromethane/methanol as eluents). 0.045 g of 2-[5,6-dimethoxy-3-(1H-pyrrolo[2,3-b]pyridin-2-yl)indol-1-yl]ethanol is obtained, the characteristics of which are as follows:
