description 2-[[(2-pyridinyl) metyl] sulfinyl]-IH-benzimidazolderivater med generell formel (V), hvor R2 betegner H, OCH3, OCHF2 eller CF3, R3 betegner H, CH3 eller OCH3/ R4 betegner H, OCH3, OCH2CF3, halogen eller nitro, R5 betegner H, CH3 eller OCH3, og N er O eller l, eller salter derav,- fremstilles ved en ny fremgangsmåte som foregår via nye mellomprodukter med generell formel (I), (II), (III) og (Va) hvor R1 betegner forgrenet eller rettkjedet Cj. 8-alkyl, C3.8-sykloalkyl, aryl, aralkyl med ^gC-atomer i alkyldelen, eller en 5-6-leddet heterosyklisk gruppe med 1,2 eller 3 heteroatomer utvalgt fra nitrogen, svovel og oksygen i den heterosykliske ring. Forbindelsene med formel (V) er biologisk aktive og/eller kan anvendes som mellomprodukter ved syntese av biologisk aktive forbindelser. (V) (D R« (Va) 2-[[(2-pyridinyl)methyl]sulfinyl]-1H-benzimidazole derivatives of general formula (V) wherein R represents H, OCH3, OCHF2 or CF3, R represents H, CH3 or OCH3, R represents H, OCH3, OCH2CF3, halo or nitro, R 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 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.
