Process of synthesis of 5-methoxy-2-[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl] sulfinyl-1 H-benzimidazole |
| abstract |
An improved process of synthesis of 5-methoxy-2-[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]sulfinyl- 1 H-benzimidazole (omeprazole) by oxidation of 5-methoxy-2[[(4-methoxy-3,5-dimethyl-2-pyridyl)methyl]thio]benzimidazole with 3-chloroperoxybenzoic acid in ethyl acetate wherein omeprazole is poorly soluble, at a temperature between −10° C. and 5° C. is disclosed. The second step is a purification of the crude product by dissolution and reprecipitation of the final product. |
