Reaction Steps

A mixture of 5-iodo-4[(4-methyl-1H-indol-5-yl)amino]nicotinonitrile (100 mg, 0.27 mmol), 2-[4-(2-methoxyethoxy)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (98 mg, 0.35 mmol), and tetrakis(triphenylphosphine)palladium(0) (16 mg, 0.014 mmol) in DME (6 mL) and saturated aqueous NaHCO3 (4 mL) was heated at 95° C. for 3 h, cooled to room temperature, and treated with water. The precipitate was filtered, washed with water, dried in vacuo, and purified by flash column chromatography (MeOH/CH2Cl2, 2% to 4%) to provide 75 mg (70%) of 5-[4-(2-methoxyethoxy)phenyl]-4-[(4-methyl-1H-indol-5-yl)amino]nicotinonitrile as a tan solid. HPLC retention time: 8.2 min.(g); MS: 399.3 (M+H); melting range: 208-210° C.; and HRMS: 399.18056.
