PROCEDURE

实验过程

1-(2-(5-Bromo-4-(thiophen-2-yl)pyrimidin-2-ylamino)ethyl)imidazolidin-2-one (0.1 g, 0.27 mmol), 4-chlorophenylboronic acid (0.085 g, 0.54 mmol), sodium carbonate (0.27 mL of 2.0 M solution, 0.52 mmol) were added to a flask containing dioxane (1 mL). The flask was flushed with nitrogen and tetrakis(triphenylphosphine)palladium (0.062 g, 0.054 mmol) was added. The reaction was heated to 80° C. overnight. The reaction was cooled down to ambient temperature and diluted with ethyl acetate and water. The organic layer was filtered through a pad of celite and washed with saturated aqueous sodium bicarbonate, water and brine. The organic layer was then dried with sodium sulfate, concentrated and purified by column chromatography using a gradient 2 to 10% of methanol in dichloromethane to afford an off-white solid. Yield=0.04 g. MS (M+H)+ 400.
