Reaction Steps

Using similar reaction conditions as described in step-ii of example-1, tert-butyl 4-(4-(3-iodo-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)phenyl)piperazine-1-carboxylate (intermediate 41) (250 mg, 0.3 mmol) was coupled with 1-(3-methoxybenzyl)-3,5-dimethyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (intermediate 53) (131 mg, 0.4 mmol) in sodium carbonate (123 mg, 1 mmol), PdCl2 (dppf) (140 mg, 0.18 mmol), Toluene/ethanol/water (2/2/1 ml) to give 40 mg (14% yield) of titled compound. MS: m/z=747.3 (M+1).
