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. 1074-41-5, name is 6-Amino-2-(methylthio)pyrimidin-4-ol, molecular formula is C5H7N3OS, 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. Quality Control of 6-Amino-2-(methylthio)pyrimidin-4-ol
General procedure: A mixture of equimolar amounts of 6-amino-2-(methylthio)pyrimidin-4(3H)-one (1) (1 mmol), ethylcyanoacetateor meldrum?s acid (2 or 5) (1 mmol) and aldehyde(3 or 6) (1 mmol) was added to a vial containinga magnetic stirring bar and [DMBSI]HSO4 (0.18 mmol,0.06g) and heated at 80 C in an oil bath. Stirring at 80C was continued until disappearance of the startingmaterials. At this stage, due to the poor solubility in theionic liquid, the product appears as a precipitate. Thereaction mixture was cooled and washed with water toextract the ionic liquid. The solid obtained was recrystallizedfrom ethanol to furnish the desired pure product.The ionic liquid was recovered from the aqueous extractsby evaporation under reduced pressure, and reusedin the next run.
With the rapid development of chemical substances, we look forward to future research findings about 1074-41-5.
