Process for the isolation and purification of an imidazole stereoisomer from a mixture of stereoisomers by selective precipitation
A method for the isolation and purification of an imidazole compound, useful as an angiotensin II receptor inhibitor compound or as a key intermediate therefor, from a mixture of it with its regioisomer in a solvent by treament of the mixture with a strong acid to effect selective precipitation of t...
