| titleOfInvention | Preparation method of DP-IV inhibitor aulogliptin intermediate |
| abstract | The present invention provides a method for preparing an alogliptin intermediate. The acid propargyl ester is reacted to obtain the product C 1-(2,5-difluorophenyl)-1-oxopent-4-alkyn-2-ylcarbamate. The invention takes a unique approach, selects a specific aulogliptin intermediate as the research direction, provides an efficient process, and the one-step reaction yield can be as high as 96%. |
