The present invention relates to a novel, efficient and industrially advantageous process for preparing perhydroisoindole derivative, particularly (S)-mitiglinide of formula (I): and pharmaceutically acceptable salts thereof. Further, it relates to novel amide intermediates of formula (VI), including salts, solvates, hydrates, polymorphs, isomers and racemic mixtures thereof useful in the process of present invention. Formula (VI): wherein R is selected from straight chain or branched C1-6 alkyl, unsubstituted or substituted aryl, unsubstituted or substituted arylalkyl. The present invention also relates to amorphous form of mitiglinide calcium, its preparation and process for its conversion to crystalline mitiglinide calcium.
本发明涉及一种新的、高效的、工业上有利的过程,用于制备过氢异吲哚衍生物,特别是式(I)的(S)-米格列酰胺及其药学上可接受的盐。此外,本发明涉及式(VI)的新的酰胺中间体,包括其盐、溶剂、水合物、多晶形、异构体和外消旋混合物,这些中间体在本发明的过程中有用。其中R选自直链或支链C1-6烷基、未取代或取代的芳基、未取代或取代的芳基烷基。本发明还涉及米格列酰胺钙的非晶态形式、其制备以及将其转化为晶体米格列酰胺钙的过程。
