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. 1074-41-5, name is 6-Amino-2-(methylthio)pyrimidin-4-ol. A new synthetic method of this compound is introduced below., Quality Control of 6-Amino-2-(methylthio)pyrimidin-4-ol
General procedure: A mixture of 6-amino-2-(alkylthio)pyrimidin-4(3H)-one 5 (1 mmol),1,3-diethyl-2-thioxodihydropyrimidine-4,6(1H,5H)-dione 6 (1 mmol),arylaldehyde (1 mmol) and [gamma-Fe2O3HAp-SO3H] (0.05 g) in EtOH (10 mL) was heated under reflux. The progress of the reaction was monitored by TLC (EtOAc/petroleum: 2/1). After completion ofthe reaction, the catalyst was separated from the reaction mixture by external magnet and reused in the next run. The reaction mixture was cooled, and the solid obtained was recrystallised from EtOH/H2O to give the desired pure product.
