DMF (5 mL) was added to a mixture of 6-(3-bromo-6-(4-methoxyphenyl)-1H-indol-1-yl)-N-methylpyrimidin-4-amine (200 mg, 0.49 mmol), K3PO4 (312 mg, 0.885 mmol) and 4-(ethoxycarbonyl)phenylboronic acid (143 mg, 0.74 mmol) and then the dissolved gas was removed. After adding Pd(PPh3)4 (85 mg, 0.075 mmol), the mixture was stirred at 100° C. for 4 hours. After adding ethyl acetate and water and 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 (70 mg) was obtained as white solid.
