Abstract
The present invention provides a process forthe purification of norethindrone (I) from mixture of dimethyl formamide-water. The present invention further provides two processes for the purification of norethindrone acetate (II) from mixture of dichloromethane-n-heptane (Process A) and from mixture of methanol-water (Process B).
