PROCESS AND INTERMEDIATES FOR THE PREPARATION OF THIENOPYRROLE DERIVATIVES |
摘要 |
<p>A process for preparing a compound of formula (I) where R<SUP>4 </SUP>and R<SUP>5 </SUP>are as defined in the specification; and R<SUP>6 </SUP>is hydrogen or a protecting group, which process comprises cyclisation of a compound of formula (II) where R<SUP>4</SUP>, R<SUP>5 </SUP>and R<SUP>6 </SUP>are as defined in relation to formula (I), and R<SUP>7 </SUP>is nitrogen-protecting group, and removing the group R<SUP>7</SUP>-, and thereafter if desired or necessary, removing any protecting group R<SUP>6 </SUP>to obtain the corresponding carboxylic acid. Novel intermediates and the use of the products in the preparation of pharmaceutical compounds is also described and claimed.</p> |
