Procedure

DMF (5 mL) was added to a mixture of 6-(3-bromo-6-(3-nitrophenyl)-1H-indol-1-yl)-N-methylpyrimidin-4-amine (300 mg, 0.710 mmol), K3PO4 (452 mg, 2.13 mmol) and 4-methoxyphenylboronic acid (215 mg, 1.41 mmol) and then the dissolved gas was removed. After adding Pd(PPh3)4 (123 mg, 0.11 mmol), the mixture was stirred at 120° C. for 2 hours. After adding ethyl acetate and water and then filtering using a diatomite pad, the organic layer was separated and the aqueous layer was extracted with ethyl acetate. The collected organic layer was washed with brine and concentrated under reduced pressure by drying with anhydrous magnesium sulfate. The residue was purified by chromatography (silica gel, EA:Hx=1:4→1:1). The target compound was obtained as white solid.
