| titleOfInvention | Process for preparing ursodeoxycholic acid di-sodium 3,7-disulfate |
| abstract | Process for preparing ursodeoxycholic acid di-sodium 3,7-disulfate comprising: a) reacting ursodeoxycholic acid with sulfamic acid to give ursodeoxycholic acid di-ammonium 3,7-disulfate; b) treating ursodeoxycholic acid di-ammonium 3,7-disulfate with organic sodium bases or inorganic sodium bases and then treating the reaction mixture with an inorganic acid until a pH between 3.0 and 4.5 is reached to give ursodeoxycholic acid di-sodium 3,7-disulfate in solution; c) removing the salts present (by filtration) and then precipitating ursodeoxycholic acid di-sodium 3,7-disulfate by diluting with an organic solvent. |
