Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1193-24-4, name is 4,6-Dihydroxypyrimidine. A new synthetic method of this compound is introduced below., Safety of 4,6-Dihydroxypyrimidine
General procedure: According to the conventional manufacturing method of the present inventors [16], under the condition containing two equivalents of triethylamine in dichloromethane at 25 , 4,6- dihydroxy-pyrimidine with 2 equivalents of Compound 2 by acylating a new and compounds 4, 6-pyrimidyl di (2-halo-benzoate) (compound 3) is prepared. After evaporation of dichloromethane, the mixture is dissolved in anhydrous THF, to remove the triethylamine hydrochloride by filtration. The concentrated residue was purified by short length silica gel (Davisil, pH = 7) was purified by column chromatography, or the Compound 3 is prepared by purification was recrystallized with 75% EtOAc / n- hexane
