Abstract
The present invention relates generally intermediates for making (R)-3-(2,3-Dihydroxypropyl)-6-fluoro-5-(2-fluoro-4-iodophenylamino)-8-methylpyrido[2,3-d]pyrimidine-4,7(3H,8H)-dione.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A compound of formula
wherein G 1 is halogen.
2 . A compound of the formula
wherein G 1 is halogen and R 3 and R 4 are independently selected from the group consisting of hydrogen and suitable hydroxy protecting groups.
3 . A compound of the formula
wherein G 1 is halogen and R 3 and R 4 are independently selected from the group consisting of suitable hydroxy protecting groups.
4 . The compound of claim 2 wherein the stereochemistry is the (R)-configuration.
5 . The compound of any one of claims 1 to 3 wherein G 1 is chloro.
6 . The compound of claim 2 wherein G 1 is chloro and R 3 and R 4 taken together are acetonide.Cited by (0)
