Process for the preparation of benzothiophene derivatives |
| abstract |
The present invention is concerned with a novel process for the preparation of thenhydroxybenzothiophene of Formula In ncomprising cyclocarbonylation of a compound of Formula IIn nwherein -OR is as defined in the specification, followed by saponification. The compoundnof Formula I is a building block of pharmaceutically active substances, e.g. 5-[4-[2-(5-methyl-2-phenyl-4-oxazolyl)ethoxy]-7-benzothiophenylmethyl]-2,4-thiazolidinedionenand the corresponding sodium salt. |
