Process for the preparation of ursodeoxycholic acid disodium 3,7-disulfate

Process for preparing the disodium salt of ursodeoxycholic acid 3,7-disulfate comprising the following steps: a) reaction of ursodeoxycholic acid with a complex of trimethylamine-sulphuric anhydride, to obtain the ursodeoxycholic acid 3,7-disulfate di-trimethylammonium reaction intermediate; b) treatment of the di-trimethylammonium salt of ursodeoxycholic acid 3,7-disulfate with organic or inorganic sodium bases to obtain the tri-sodium salt of ursodeoxycholic acid 3,7-disulfate; c) treatment with an inorganic acid in presence of isopropanol up to a pH comprised in the range between 3.0 and 4.5, to obtain the disodium salt of ursodeoxycholic acid 3,7-disulfate in solution; d) removal of the salts present and obtaining the disodium salt ofursodeoxycholic acid 3,7-disulfate.
