Versuchsvorschrift
General procedure D was used to deprotect 0.65 mmol of 4 and immediately coupled to 0.975 mmol of 40. After flash chromatography 0.96 g (0.25 mmol) of the title product was recovered. 1H NMR (300 MHz, CDCl3) δ 7.76 (d, J=8.8, 2H), 7.49-7.21 (m, 6H), 7.00 (d, J=8.7, 2H), 6.80 (d, J=8.3, 1H), 6.65 (d, J=12.0, 3H), 5.22-5.08 (m, 1H), 5.03 (s, 2H), 1.65 (d, J=7.2, 3H).
