A common compound: 504-17-6, name is 4,6-Dihydroxy-2-mercaptopyrimidine,molecular formula is C4H4N2O2S, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below., 504-17-6
General procedure: To a mixture of an aromatic aldehyde (0.25 mmol), 2-thiobarbituric acid(0.5 mmol), ammonium acetate (0.3 mmol), [H-NMP]+[HSO4]- (12 mol%)and water (2 ml) was added. Then, ultrasonic probe was directly immersed inthe resulting mixture. The progress of the reactions was monitored by TLCuntil conversion of the starting materials was satisfactory. After completion ofthe reaction, the solvent was evaporated and the precipitate was washed withEtOH and hot water to afford the pure product. All products were identified byphysical and spectroscopic data. The synthesis of the compounds 4b and 4j wasinvestigated but unfortunately even after 24 h, only a trace amount of productwas observed by TLC, that is why we could not reported the spectroscopic dataof them.
With the rapid development of chemical substances, we look forward to future research findings about 504-17-6.
