Analyzing the synthesis route of 22900-83-0

22900-83-0 Ethyl 2-bromo-4-methylthiazole-5-carboxylate 2824057, athiazole compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.22900-83-0,Ethyl 2-bromo-4-methylthiazole-5-carboxylate,as a common compound, the synthetic route is as follows.

Part F: Ethyl 4-methyi-2-morpholin-4-yl-1.3-thiazole-5-carboxylate; A mixture of ethyl 2-bromo-4-methyl-ls3-thiazole-5-carboxylate (950 mg, 3.80 mmol), morpholine (0.5 mL, 5.70 mmol), and potassium carbonate (1.1 g, 7.60 mmol) in 4.0 ml of NMP is heated to 130 ¡ãC for 1.5 h. The reaction is cooled to RT, and the NMP is removed in vacuo. The residue is partitioned between CH1CI2 and water (20 ml each), and the layers are separated. The aqueous layer is extracted once more with 20 ml of CH2CI2, and the combined organic extracts are dried (Na2SQ4), filtered, and evaporated in vacuo to give the title compound as an off-white solid. Mass spec. (257.06, M+H)., 22900-83-0
