Abstract:
A precursor phase of the magnesium tetrahydrate salt of an omeprazole enantiomer, and also processes for preparing it and its use for the preparation of the magnesium tetrahydrate salt are described. Crystals of the magnesium tetrahydrate salt thus obtained, and their uses, especially in the synthesis of the dihydrate form A of the magnesium salt of the enantiomer or as medicament are also disclosed.
