5-Methyl-3,4-diphenylisoxazole Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
5-Methyl-3,4-diphenylisoxazole is synthesis The key intermediate of Parecoxib Sodium (Parecoxib Sodium).Parecoxib Sodium is by the Pfizer of the U.S. The cox 2 inhibitor of company's research and development, listed in European Union in 2002, trade name Dynastat, is used for The short term therapy of postoperative pain.
Synthese
In four mouthfuls of round-bottomed flasks of a 1L add compound 2 (40g), methanol (400mL), 7.7% Aqueous sodium carbonate (400mL), is heated to 70°C, after stirring reaction 2h, and TLC plate monitoring raw material Fundamental reaction is complete, and solution is divided into solid-liquid biphase, is extracted with ethyl acetate, collected organic layer, with anhydrous Sodium sulfate is dried, and vacuum obtains white solid, HPLC purity: 94.9% after being spin-dried for.White solid uses 40ml ethyl acetate and the mixed solvent recrystallization of 120ml normal hexane (1:3) again, Obtaining target compound is white solid 34.2g, yield 92%, HPLC purity: 99.7%.m.p.97-98??￡?
