参考标题: Process For Preparation Of Carvedilol Procede Pour Preparer Du Carvedilol 摘要:The Invention Solves A New Method Of Preparation Of Carvedilol For Pharmaceutical Use. In The Synthesis Of Carvedilol A Reaction Of 4-(Oxirane-2-Ylmethoxy)-9H-Arbazole (II) With 2-(2-Methoxyphenoxy)Ethylamine Salts (Iv) In The Presence Of A Base, In An Alcohol Having The Number Of Carbons C2 To C5 As A Solvent, At An Elevated Temperature, Is Used. After Processing Of The Crude Reaction Mixture Crude Carvedilol Is Obtained, Which Is Purified By Crystallization From Ethylacetate With An Addition Of Activated Carbon And The Final Substance Is Formulated By Crystallization From Ethylacetate.
