Process for the preparation of key intermediates of omarigliptin |
| abstract |
An improved process for the preparation of a key intermediate for the synthesis of the active ingredient Omarigliptin is provided. The key intermediate is a compound having the following formula (I) n nwherein R 1 is propargyl or allyl group and P is an amine protecting group. The compound of formula (I) is prepared by converting a compound of formula (IV)n n nby an amination reaction to a compound of formula (III),n n nwhich is then protected to provide a compound of formula (II),n n nwhich is then alkylated to provide the compound of formula (I). |
