Reaction Steps

To a vial containing (E)-tert-butyl 3-(4-((2-(4-(difluoromethyl)phenyl)-6-hydroxybenzo[b]thiophen-3-yl)oxy)phenyl)acrylate (30 mg, 0.061 mmol) in THF (1.0 mL) was added HCl (4.0 N in dioxane, 0.4 mL, 1.600 mmol). The resulting mixture was stirred at 50° C. for 12 h after which time the reaction was concentrated in vacuo and purified by reverse phase HPLC (neutral condition, 3% 1-propanol in 10-100% CH3CN/H2O) to afford (E)-3-(4-((2-(4-(difluoromethyl)phenyl)-6-hydroxybenzo[b]thiophen-3-yl)oxy)phenyl)acrylic acid (21 mg, 0.048 mmol, 79% yield). LC/MS (m/z, M−H): 437.5.
