Zusammenfassung

Bromierung von 2-Methyl-3-acetyl-benzo[b]thiophen ergab 2-Methyl-3-bromacetyl-benzo[b]thiophen, das beim Umsetzen mit Dimethylamin, Morpholin und N-Methylpiperazin die entsprechend basisch substituierten 3-Acetylverbindungen lieferte. Diese wurden mit LiAlH4 zu den α-Hydroxyverbindungen reduziert.

In ähnlicher Weise wurde auch 3-Diäthylaminoacetyl-benzo[b]thiophen dargestellt.

Abstract

Bromination of 2-methyl-3-acetyl-benzo[b]thiophene gave 2-methyl-3-bromacetyl-benzo[b]thiophene, which reacted with dimethylamine, morpholine and N-methylpiperazine to give the corresponding base-substituted 3-acetyl derivatives. These were reduced by LiAlH4 to the α-hydroxy compounds.

Similarily 3-diethylaminoacetyl-benzo[b]thiophene was synthesized.
