Procedure

4-Chloro-2-[1-methyl-5-methoxy-6-benzyloxy)-1H-indol-3-yl]-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine is prepared by following the procedure described in example 89c, but using 2.5 g of 4-chloro-2-(5-methoxy-6-benzyloxy-1H-indol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine and 0.335 ml of methyl iodide. After purification by flash chromatography (silica, 40/60 by volume ethyl acetate/cyclohexane as eluents, argon), 2.1 g of 4-chloro-2-(1-methyl-5-methoxy-6-benzyloxy-1H-indol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine are obtained, the characteristics of which are as follows:
