Abstract
Fremgangsmåte for fremstilling av 2-[[(2-pyridinyl)metyl]sulfinyl]-lH- bcnzimidazoler og nye forbindelser til anvendelse for dette formål Fremgangsmåte for fremstilling av 2-[[2- pyridinyl)metyl]sulfinyl]-l-H- benzimidazolderivater med generell formel (1), hvor R2 betegner H, OCH3, OCHF2 eller CF3; R3 betegner H, CH3 eller OCH3; R' betegner H, OCH3, OCH2CF3, eller halogen, slik som Cl, Br eller F; og R5 betegner H, CH3 eller OCH3, eller salter derav, omfattende reduksjon av en forbindelse med generell formel (II), eller et salt derav, hvor R2, R3, R4 og R5 er som definert ovenfor, i et alkoholisk løsningsmiddel, idet reduksjonen utføres ved anvendelse av et tiobisamin som reduksjonsmiddel i nærvær av en mineralsyre, og hvis ønskelig, omdannelse av en forbindelse oppnådd i fri form til et salt derav, eller vice versa. Nye mellomprodukter med formel (II) er også beskrevet. Forbindelsene med formel (I) er biologisk aktive og/eller kan anvendes som mellomprodukter ved syntese av biologisk aktive forbindelser.
