A kind of industrial preparation method of improved mitiglinide calcium |
| abstract |
The present invention is an improved preparation method of mitiglinide calcium (I), which is characterized in that: the preparation method successively comprises step 1: preparation of 2-benzylidene succinic acid; step 2: (S)-2-benzyl Preparation of phenylsuccinic acid; Step 3: 2-(S)-Benzyl-4-oxo-(cis-perhydroisoindol-2-yl)butanoic acid; Step 4: Preparation of mitiglinide calcium . The invention provides an economical and practical method for industrialized preparation of mitiglinide calcium with simple operation, short reaction period and high yield. |
