用途有機合成原料。
使用2,4-Dichloropyrimidine was used in the synthesis of medicinally important 4-aryl-5-pyrimidinylimidazoles.
一般的な説明2,4-Dichloropyrimidine is a human skin sensitizer. It undergoes effective one-pot, regioselective double Suzuki coupling reaction to yield diarylated pyrimidines.
製造方法Obtained by chlorination of uracil. Add uracil, phosphorus trichloride, and xylene amine into the reaction pot, heat to 130 ℃, reflux for about 45min, slightly cool, put in crushed ice, that is, the precipitation of purple solid, filtered while hot and not dissolved, washed with ice water, vacuum drying, a kind of purple crude, decolorized with petroleum ether (boiling range of 60-90 ℃), recrystallized, obtained 2,4-dichloropyrimidine.
