Reaction Steps
To a round bottomed flask containing 2,4-dichloroquinazoline (800 mg, 4.02 mmol) was added indol-5-boronic acid (647 mg, 4.02 mmol), dichloro-((bis-diphenylphosphino)-ferrocenyl)-palladium (II) (complex with methylene chloride, 235 mg, 0.32 mmol), triethylamine (1.5 mL, 10 mmol), dimethoxyethane (20 mL), and water (0.5 mL). The reaction mixture was heated at 80° C. for 14 h, then cooled to rt and diluted with ethyl acetate. The organic layer was washed with saturated sodium bicarbonate, dried over sodium sulfate, filtered, and concentrated on a rotary evaporator. The material was purified by flash column chromatography to afford 2-chloro-4-(1H-indol-5-yl)quinazoline as a brown solid (740 mg, 66%).
