Reaction Steps

A mixture of 5-bromo-N-(1-(3-(tert-butyldimethylsilyloxy)propyl)-1H-benzo[d]imidazol-2-yl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-indazol-3-amine (from Step 1: 191 mg, 0.000303 mol), 4-methoxypyridin-3-yl-3-boronic acid (64 mg, 0.00042 mol) and (1,1′-bis(diphenylphosphino)-ferrocene)dichloropalladium(II), complexed with dichloromethane (1:1) (41 mg, 0.000050 mol), was dissolved in 1,4-dioxane (3.04 mL). To this mixture was added 2.0 M sodium carbonate in water (0.76 mL) with stirring. The mixture was flushed with argon sealed and heated at 110° C. After 3 hours, the mixture was diluted with methylene chloride, washed with water and brine, the organic phase dried over magnesium sulfate, filtered, and concentrated. The residue was dissolved in methylene chloride and purified by flash chromatography (50-100% ethyl acetate-0.3% triethylamine in hexanes) to give 132 mg (66%) of the title compound.
