With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.504-17-6, name is 4,6-Dihydroxy-2-mercaptopyrimidine, molecular formula is C4H4N2O2S, molecular weight is 144.1518, as common compound, the synthetic route is as follows.name: 4,6-Dihydroxy-2-mercaptopyrimidine
General procedure: A mixture of aldehyde (1 mmol), malanonitrile (1 mmol), barbituricor thiobarbituric acid (1 mmol), and DES (0.1 g, 36 mol%)was stirred in refluxing water (2 mL) for an appropriate period oftime. The reaction progress was followed by TLC (eluent: EtOAc: nhexane).After completion of the reaction, the mixture was dilutedwith water (4 mL) and filtered off. Finally, the solid product wasrecrystallized from warm ethanol if necessary.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,504-17-6, 4,6-Dihydroxy-2-mercaptopyrimidine, and friends who are interested can also refer to it.
