Esomeprazole magnesium dihydrate synthesis essay

One of the most important features of the esomeprazole procedure is that amine additives increase the enantioselectivity of the oxidation process. The NMR studies of the presumed reaction intermediates show that under catalytic conditions the amines are able to coordinate to titanium and dissociate the coordinated imidazole substrate.

In one embodiment, the present invention provides, as depicted in scheme I, a novel process for the preparation of esomeprazole magnesium dihydrate using the novel polymorph Form II of intermediate Esomeprazole magnesium dihydrate is a leading proton pump inhibitor.
