7-Fluoro-2-(4-hexylphenyl)-5-octyloxybenzo[b]thiophene is obtained by reacting 3-fluoro-4-methoxythiophenol (obtainable analogously to Reference 7 from 3-fluoro-4-methoxyaniline [366-99-4]) and 4-hexylphenacyl bromide analogously to Reference 5 to give 7-fluoro-2-(4-hexylphenyl)-5-methoxybenzo[b]thiophene, ether cleavage by means of hydrobromic acid/acetic acid to give 7-fluoro-2-(4-hexylphenyl]-5-hydroxybenzo[b]thiophene and Williamson ether synthesis using octyl bromide in 2-butanone in the presence of potassium carbonate.
