Application of 1193-24-4 ,Some common heterocyclic compound, 1193-24-4, molecular formula is C4H4N2O2, 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.
0.5 mol of 4,6-dihydroxypyrimidine was added to the reaction vessel,Solvents Trichloromethane,0.05 mol of pyridine catalyst,Then slowly into the phosgene 1.5mol,The reaction temperature was controlled within 50 C,After reaction for 3 h,After the completion of the reaction, the excess solvent chloroform was distilled off under reduced pressure,To give a 4,6-dichloropyrimidine solution,And then filtered, concentrated and crystallized to give 4,6-dichloropyrimidine as white needles.The yield of product 4,6-dichloropyrimidine prepared by the above method was 78% and the purity was 80%.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1193-24-4, its application will become more common.
