Procedure
A solution of (S,E)-3-(4-(3-(tert-butoxy)-3-oxoprop-1-en-1-yl)phenoxy)-2-(2-isopropylphenyl)benzo[b]thiophen-6-yl 2-((tert-butoxycarbonyl)amino)-3-methylbutanoate (106.8 mg, 0.156 mmol) in HCl (2.0 mL, 4N in 1,4-dioxane) was stirred at room temperature for 18 hours after which time the mixture was concentrated in vacuo to remove HCl and 1,4-dioxane. The resulting crude material was then triturated with heptane (2×) to obtain (S,E)-3-(4-((6-((2-amino-3-methylbutanoyl)oxy)-2-(2-isopropylphenyl)benzo[b]thiophen-3-yl)oxy)phenyl)acrylic acid hydrochloride (54.1 mg, 0.094 mmol, 85% yield). 1H NMR (400 MHz, CD3OD) δ ppm=7.81 (d, J=2.02 Hz, 1H), 7.42-7.62 (m, 4H), 7.25-7.42 (m, 3H), 7.09-7.26 (m, 2H), 6.86 (d, J=8.59 Hz, 2 H), 6.32 (d, J=15.66 Hz, 1 H), 4.29 (d, J=5.05 Hz, 1H), 3.18 (s, 1 H), 2.44-2.60 (m, 1 H), 1.12-1.35 (m, 12H) HRMS (m/z, MH+): 530.1988.
