But using 0.160 g of 2-[1-(2-{3-[4-chloro-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridin-2-yl]-5,6-dimethoxyindol-1-yl}ethyl)piperidin-4-yl]ethanol and 0.58 g of potassium hydroxide in 10 ml of methanol. After flash chromatography on a silica column [eluent: dichloromethane/methanol (80/20 by volume)], 0.078 g of 2-(1-{2-[3-(4-chloro-1H-pyrrolo[2,3-b]pyridin-2-yl)-5,6-dimethoxyindol-1-yl]ethyl}piperidin-4-yl)ethanol is thus obtained in the form of a solid, the characteristics of which are as follows:
