Novel process for preparation of 19-norsteroids |
| abstract |
The present invention provides a single pot process for the synthesis of 19-Norethisterone of Formula (I), comprising contacting 19-Norandostene-3,17-dione of Formula–II with a first base, an organic gas/solution and an acid to obtain 19- Norethisterone of Formula-I; and purifying the 19- Norethisterone of Formula-I thus obtained by refluxing and subsequently washing with organic solvent. |
