    摘要: The present invention provides a process comprising admixing a thioether with about 1.05 to about 1.6 molar equivalents of an active chlorine-containing oxidant, preferably sodium hypochlorite, and about 2.5 to about 5.0 molar equivalents of an alkali metal base; and recovering a sulfoxide that is preferably pantoprazole, lansoprazole, omeprazole, or rabeprazole. The process may further comprise contacting the sulfoxide with a source of sodium ions, preferably sodium hydroxide, to produce the sodium salt of the sulfoxide. The invention also relates to novel chlorinated derivatives of pantoprazole including 5-(difluoromethoxy)-2-[[(3,4-dimethoxy-2-pyridinyl)-chloromethyl]sulfinyl]-1H-benzimidazole and 5-(difluoromethoxy)-2-[[(3,4-dimethoxy-2-pyridinyl)-chlorohydroxymethyl]sulfinyl]-1H-benzimidazole and processes for making them. The invention also relates to processes of quantifying and identifying a compound other than pantoprazole in a mixture of pantoprazole and at least one other compound.

    摘要: Processes are provided for preparing mupirocin calcium dihydrate from pseudomonic acid in a two phase system by using an organic carboxylate.A highly pure composition of amorphous mupirocin calcium is provided, and processes for its preparation by solvent removal, lyophilization and precipitation with use of an anti-solvent. Pharmaceutical compositions of amorphous form, and methods of using them to treat infections are also provided.Also provided are combined processes for preparing mupirocin calcium dihydrate and amorphous, by producing amorphous form first, followed by conversion of amorphous form into the dihydrate through crystallization from an aqueous solution. Also provided are processes for removing the water of crystallization of the dihydrate to obtain mupirocin calcium anhydrate.
