Procedure
General procedure D was used to deprotect 0.210 g (1.23 mmols) of 4. The product was immediately carried on using general procedure F and coupled to 1.23 mmols of 10. The title product was purified with flash chromatography using a solvent system of ethyl acetate and hexanes (1:3) to yield 0.106 g (0.41 mmols). 1H NMR (500 MHz, CDCl3) δ 7.74-7.68 (m, 2H), 7.25 (d, J=8.2, 2H), 6.61 (s, 1H), 5.20-5.11 (m, 1H), 2.70-2.61 (m, 2H), 1.66 (t, J=6.6, 3H), 1.60 (dd, J=7.3, 14.9, 2H), 1.37-1.22 (m, 6H), 0.88 (t, J=6.8, 3H). 13C NMR (126 MHz, CDCl3) δ 173.95, 166.58, 148.00, 148.00, 131.31, 129.95, 128.78, 128.62, 127.20, 127.03, 119.42, 77.27, 77.02, 76.76, 52.57, 48.42, 36.24, 35.85, 31.63, 31.10, 28.87, 22.56, 19.57, 18.68, 14.07.
