PROCEDIMIENTO PARA PREPARAR 2-BROMO-<-ERGOCRIPTINA Y SUS SALES ACIDAS COMPLEMENTARIAS |
摘要 |
<p>The invention relates to a novel process for the preparation of 2-bromo- alpha -ergocryptine and its acid addition salt by brominating alpha -ergocryptine in such a way that the bromination is carried out at room temperature by using a dimethylsulphoxide-hydrogen bromide mixture containing no more 0.02% of water and, if desired, converting the thus-obtained 2-bromo- alpha -ergocryptine to an acid addition salt in a known manner.</p> |
