Description and Uses
5-Methoxy-2-benzimidazolethiol may be used in the preparation of compounds present as contaminants in omeprazole, such as 5-methoxy-2-[[(4-methoxy-3,5-dimethyl-2-pyridinyl)methyl]sulfonyl]-1H-benzimidazole and 5-methoxy-2-[[(4-methoxy-3,5-dimethylpyridin-2-yl-1-oxide)methyl]sulfonyl]-1H-benzimidazole. It may be used in the synthesis of tris[μ-1,2-bis(diphenylphosphino)ethane]-1:2κ2P:P′;1:3κ2P:P′;2:3κ2P:P′-di-μ-bromido-1:2κ4Br:Br-bromido-3κBr-tricopper(I) acetone hemisolvate.
