    摘要: The present invention is concerned with a novel process for the preparation of the hydroxybenzothiophene of formula I comprising cyclocarbonylation of a compound of formula II wherein Y is as defined in the specification, followed by saponification. The compound of 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-thiazolidinedione and the corresponding sodium salt which are from agents useful in the treatment of diabetes.
