Hydrochloric Acid → (E)-3-(4-((6-methoxy-2-(2-(methoxymethyl)phenyl)benzo[b]thiophen-3-yl)oxy)phenyl)acrylic acid

Participants

Reaction Steps

To a solution of (E)-methyl 3-(4-((6-methoxy-2-(2-(methoxymethyl)phenyl)benzo[b]thiophen-3-yl)oxy)phenyl)acrylate (86.6 mg, 0.188 mmol) in MeOH (3.0 mL) was added LiOH (2.0N aqueous, 0.564 mL, 1.128 mmol). The resulting mixture was stirred at room temperature for 48 h after which time the reaction was brought to pH 7 by addition of 1N HCl, the neutralized reaction was then concentrated in vacuo to afford (E)-3-(4-((6-methoxy-2-(2-(methoxymethyl)phenyl)benzo[b]thiophen-3-yl)oxy)phenyl)acrylic acid (45.9 mg, 0.103 mmol, 55% yield). LC/MS (m/z, MH+): 447.0.
