Reaction Steps

A solution of 2-(5-benzyloxy-6-methoxy-1-methyl-1H-indol-3-yl)-1-(toluene-4-sulfonyl)-1H-pyrrolo[2,3-b]pyridine [6.26 g, Reference Example 13(e)] in acetonitrile (500 mL) was treated with sodium iodide (4.38 g) followed by trimethylsilyl chloride (3.17 mL). The mixture stirred at 40° C. for 3 hours then treated with further portions of sodium iodide (4.38 g) and trimethylsilyl chloride (3.17 mL). After stirring at 40° C. for a further 12 hours the reaction mixture was evaporated. The residue was treated with water (200 mL) and the mixture was extracted three times with ethyl acetate (200 mL). The combined extracts were dried over magnesium sulfate then evaporated. The residual brown foam was triturated with ethyl acetate and diisopropyl ether to give the title compound (3.04 g) as a light brown solid, m.p. 211-214° C. HPLC (METHOD A): RT=9.30 minutes.
