Abstract (en)
[origin: WO9840378A1] 2-[[(2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole derivatives of general formula (V) wherein R<2> represents H, OCH3, OCHF2 or CF3, R<3> represents H, CH3 or OCH3, R<4> represents H, OCH3, OCH2CF3, halo or nitro, R<5> represents H, CH3 or OCH3, and n is 0 or 1, or salts thereof, are prepared by a new process proceeding via novel intermediates of general formulae (I), (II), (III) and (Va) wherein R<1> represents branched or straight C1-8-alkyl, C3-8-cycloalkyl, aryl, aralkyl having 1-8 C-atoms in the alkyl moiety, or a 5- or 6-membered heterocyclic group having one, two or three hetero atoms selected from nitrogen, sulfur and oxygen in the heterocyclic ring. The compounds of formula (V) are biologically active and/or may be used as intermediates in the synthesis of biologically active compounds.
