Crystallization of 1alpha-Hydroxy-2-Methylene-18,19-Dinor-Homopregnacalciferol |
| abstract |
A method of purifying 1α-hydroxy-2-methylene-18,19-dinor-homopregnacalciferol to obtain 1α-hydroxy-2-methylene-18,19-dinor-homopregnacalciferol in crystalline form using precipitation with hexane from ethyl acetate. A method of preparing 1α-hydroxy-2-methylene-18,19-dinor-homopregnacalciferol crystals acceptable for X-ray experiment using precipitation with hexane from benzene by diffusive exchange of the solvents is also described. |
