These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,13544-44-0, its application will become more common.

Reference of 13544-44-0 ,Some common heterocyclic compound, 13544-44-0, molecular formula is C4HCl2IN2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

While being cooled with ice, 3.55 mL of propylamine was added to 83 mL of a tetrahydrofuran solution containing 5.77 g of 2,4-dichloro-5-iodopyrimidine synthesized according to the method described in WO2008/155140A1 and 7.86 mL of N,N-diisopropylethylamine, and the mixture was stirred for 1 hour at room temperature. Then, water and ethyl acetate were added to the reaction mixture. The organic layer was fractionated, and the water layer was extracted using ethyl acetate. The organic layer and the extract were mixed together, washed sequentially with a 1.0 mol/L aqueous hydrochloric acid solution, water, a saturated aqueous sodium hydrogen carbonate solution, and a saturated aqueous sodium chloride solution, and then dried over anhydrous magnesium sulfate. The solvent was distilled away under reduced pressure, thereby obtaining 6.44 g of 2-chloro-5-iodo-N-propylpyrimidin-4-amine in the form of oil. MS m/z(M+H): 298.3
