YieldReaction ConditionsOperation in experiment
73% With hydrogen bromide; bromine; sodium nitrite; at -20 - 20℃; for 3h; 50 mL of 48% HBr was added to 10 g (40 mmol) of <strong>[40230-24-8]2-amino-4,6-diphenylpyrimidine</strong> and stirred to obtain a solution. The solution was then cooled down to about -20 C., and 2.5 mL (48 mmol) of bromine was added dropwise thereto. 2.8 g (40 mmol) of sodium nitrite was then added and the resulting reaction mixture was stirred at room temperature for about 3 hours. After completion of the reaction, the reaction mixture was extracted using ethyl acetate. The organic layer was then dried using anhydrous magnesium sulfate and the solvent was removed by distillation under reduced pressure. The residue was purified using column chromatography to obtain 9.1 g of 2-bromo-4,6-diphenylpyrimidine (Yield: 73%).
