1,4-DIHYDRO-2-(METHYLTHIO)-4-OXO-5-PYRIMIDINE-CARBOXYLATE ACID ETHYL ESTER Chemische Eigenschaften,Einsatz,Produktion Methoden

• Verwenden

  1,4-Dihydro-2-methylmercapto-4-oxo-5-pyrimidinecarboxylic acid ethyl ester can be used as several synthetic intermediates and pharmaceutical intermediates, mainly used in laboratory research and development process and pharmaceutical and chemical production process.

• Synthese

  Methylthiourea sulfate (75.2g, 0.4mol) was added to 16% NaOH (250mL, 1.18mol) solution and stirred for 30min, then diethyl ethoxymethylenemalonate (103.4g, 0.48 mol) was dissolved in 160 mL of ethanol and slowly dropped into the reaction solution. After the dropwise addition was completed, the reaction was carried out at room temperature for 10 h.When a large amount of white solid was precipitated, carry out suction filtration, wash with water, and vacuum dry to obtain a white solid (84.7g, 99.7%); ESE-MS (m/z): 249[M+H]+, 236.9[M+Na]+ , after verification, the product is 1,4-dihydro-2-methylmercapto-4-oxo-5-pyrimidinecarboxylic acid ethyl ester.
