Electric Literature of 4318-56-3, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 4318-56-3, name is 6-Chloro-3-methylpyrimidine-2,4(1H,3H)-dione, molecular formula is C5H5ClN2O2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
General procedure: 6-Chloropyrimidine-2,4(1H, 3H)-dione derivatives 1 (1.0 mmol) and N-hydroxyformimidoyl chloride derivatives 2 (1.2 mmol) were combined and dissolved in methanol (15mL), followed by the addition of triethylamine (3.0 mmol). Subsequently, the reaction mixture was stirred in a round-bottom flask (25mL) at room temperature for 5h. After completion of the reaction as indicated by TLC, the mixture was evaporated by rotary evaporator, extracted with ethyl acetate, dried over Na2SO4, then concentrated and purified by flash column chromatography (PE/EA=5:1) to yield compounds 3a-t.
According to the analysis of related databases, 4318-56-3, the application of this compound in the production field has become more and more popular.
