Title (EN) PROCESS AND INTERMEDIATES FOR THE PREPARATION OF THIENOPYRROLE DERIVATIVES
(FR) PROCEDE ET PRODUITS INTERMEDIAIRES POUR LA PREPARATION DE DERIVES DE THIENOPYRROLE
Abstract: front page image
(EN)Novel Process and Intermediates. A process for preparing a compound of formula (I) where R4 and R5 are as defined in the specification; and R6 is hydrogen or a protecting group, which process comprises cyclisation of a compound of formula (II) where R4, R5 and R6 are as defined in relation to formula (I), and R7 is a nitrogen protecting group, and removing the group R7, and thereafter if desired, removing any protecting group R6. Novel intermediates and the use of these in the formation of pharmaceutical compounds is also described and claimed.
(FR)L'invention concerne un nouveau procédé pour préparer un composé de formule (I), dans laquelle R4 et R5 sont tels que définis dans la description ; et R6 représente hydrogène ou un groupe de protection. Ledit procédé comprend la cyclisation d'un composé de formule (II), dans laquelle R4, R5 et R6 sont définis par rapport à la formule (I), et R7 représente un groupe protecteur d'azote, puis l'élimination, si nécessaire, du groupe de protection R6. L'invention concerne de nouveaux groupes intermédiaires et l'utilisation de ces derniers dans la formation de composés pharmaceutiques.
