| titleOfInvention | PROCEDURE FOR THE SYNTHESIS OF OMEPRAZOL |
| abstract | PROCESS FOR SYNTHESIS OF OMEPRAZOLE, characterized in that the reaction steps of 5-methoxy-2 - ((4-methoxy-3,5-dimethyl-2-pyridinyl) methylthio) -1H-benzimidazole (compound I) with m-chloroperoxybenzoic acid in methylene chloride solution, at a constant pH of about 8.0 to 8.6, extracting the reaction mixture with aqueous NaOH, separating the aqueous phase from the organic phase, and adding the alkyl formate to the aqueous phase, thereby crystallizing omeprazole. The application contains 8 more dependent requests. |
