Method for producing intermediate compound for pharmaceutical synthesis |
| abstract |
The present invention can produce a compound of formula (2), which is an intermediate used to synthesize dipeptidyl peptidase IV enzyme-inhibiting diabetes therapeutic agent, with high purity through a 1) oxazolidinone cyclization reaction and a deprotization reaction to convert it to amide , 2) it is possible to increase the yield and productivity by stabilizing the production process, and 3) to achieve the improvement effect of reducing the raw material cost by using the starting material of the inexpensive sample. |
