Methanol → Tert-butyl 3-(4-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)phenyl)propenoate

Participants

Reaction Steps

To a solution of (E)-tert-butyl 3-(4-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)phenyl)acrylate (27 mg, 0.06 mmol) in 4:1 MeOH:DCM (2.5 mL) was added palladium on carbon (10% wt., 0.59 mg, 5.53 μmol). The reaction was stirred at room temperature under a hydrogen balloon for 12 h after which the reaction was purged with nitrogen and filtered through Celite™. The remaining palladium was washed with DCM (30 mL) and the resulting solution was concentrated in vacuo to afford tert-butyl 3-(4-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)phenyl)propenoate (27 mg, 0.06 mmol, 100% yield) which was used without further purification. LC/MS (m/z, MH+): 491.3.
