1,4-Dibromobutane → HCID 23296311, compound

Participants

Reaction Steps

A slurry of 4.04 g (11 mmol) of 2-(4-Methoxyphenyl)-3-(3-hydroxyphenyl)-6-methoxybenzo[b]thiophene, 1,4-dibromobutane 26.3 mL (220 mmol), and 3.5 g (25.3 mmol) of K2CO3 in 200 mL of 2-butanone was preapared. The reaction mixture was heated to reflux for two hours, then filtered, and evaporated to dryness. The resulting oil was chromatographed on a silica gel column eluted with a linear gradient begining with EtOAc-hexane (1:9) (v/v) and ending with EtOAc-hexane (1:4) (v/v). The desired fractions were combined and evaporated to a yellow oil. This yielded 5 g of the title compound.
