Participants

Reaction Steps

But using 2.9 g of 2-iodo-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine, 2.34 g of 1-tert-butyloxycarbonyl-5,7-dimethoxy-1H-indole-3-boronic acid and 19 ml of a saturated aqueous solution of sodium hydrogen carbonate in 63 ml of dimethylformamide, and 0.42 g of tetrakis(triphenylphosphine)palladium is added. After flash chromatography on a silica column [eluent: cyclohexane/ethyl acetate (70/30 by volume)], 0.26 g of 2-(5,7-dimethoxy-1H-indol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine is thus obtained in the form of a solid, the characteristics of which are as follows:
