Electric Literature of 1074-41-5, 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.
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.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 1074-41-5, 6-Amino-2-(methylthio)pyrimidin-4-ol.
