Reaction Steps

{1-[2-(5,6-Dimethoxy-1-methyl-1H-indol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]azetidin-3-yl}carbamic acid tert-butyl ester is prepared as described in Example 200b starting with 0.14 g of 4-chloromethyl-2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine and 0.118 g of azetidin-3-ylcarbamic acid tert-butyl ester instead of the piperid-4-ol used in Example 200b. After purification by flash-pack chromatography (SiO2, dichloromethane/methanol 95/5 by volume as eluent), 0.135 g of {1-[2-(5,6-dimethoxy-1-methyl-1H-indol-3-yl)-1H-pyrrolo[2,3-b]pyrid-4-ylmethyl]azetidin-3-yl}carbamic acid tert-butyl ester is obtained, the characteristics of which are as follows:
