    Abstract: The present invention describes a process for the synthesis of ursodeoxycholic acid wherein the purification of the crude ursodeoxycholic acid (containing approximately 13-15% of chenodeoxycholic acid impurity) takes place first passing through a salification with imidazole and a subsequent purification via "methyl ester", which allows a finished product with an extremely low content of known "cheno and "litho" impurities to be obtained. The present invention also describes the recovery steps of cholic acid and 3α-hydroxy-7-ketocholanic acid from the mother liquors of process intermediates.
