Zusammenfassung

Eine Gruppe N-substituierter {2-Methyl-benzo[b]thienyl-(3)}-acetamide wurde zu den entsprechenden 1,1-Dioxiden oxydiert, deren katalytische Hydrierung {2-Methyl-2,3-dihydro-benzo[b]thienyl-(3)}-acetamid-S,S-dioxide ergab. Die letzteren wurden mittels LiAlH4 zu N-substituierten 2-Methyl-3-(β-aminoäthyl)-2,3-dihydro-benzo[b]thiophenen reduziert.

Abstract

N-substituted {2-methyl-benzo[b]thienyl-(3)}-acetamides were oxidized to the corresponding 1,1-dioxides, catalytic hydrogenation of which gave N-substituted {2-methyl-2,3-dihydro-benzo[b]thienyl-(3)}-acetamide-S,S-dioxides. The latter were reduced by LiAlH4 to give N-substituted 2-methyl-3-(β-amino-ethyl)-2,3-dihydro-benzo[b]thiophenes.
