Procedure
Sodium iodide (0.060 g, 0.408 mmol) and compound 19 (0.020 g, 0.034 mmol) were diluted with dioxane (8 mL), and ethylamine (0.020 mL, 0.408 mmol, 70 wt. % solution in water) was added dropwise. The mixture was stirred at reflux for 26 h. The mixture was diluted to a volume of 200 mL with CHCl3, washed with H2O (2×50 mL) and saturated aq NaCl (50 mL), dried over anhydrous sodium sulfate, and concentrated. The residue was purified by flash column chromatography (SiO2, ˜40 g), eluting with a gradient of 0.5% MeOH in CHCl3, to yield the product 24 as a solid (0.009 g, 46%): mp 187-188° C. (dec). IR (film) 1648, 1553, 1392, 1254, 1116, 1033, 785 cm−1; 1H NMR (CDCl3) δ 7.53 (s, 1H), 7.24 (s, 1H), 6.90 (s, 1H), 6.60 (s, 1H), 5.89 (s, 2H), 4.06 (s, 2H), 3.85 (s, 6H), 3.72 (s, 3H), 3.49-3.38 (m, 4H), 3.19-3.12 (m, 9H), 2.25-2.19 (m, 4H); ESIMS m/z 550 (MH+); HRESIMS m/z 550.2553 (MH+), calcd for C30H36N3O7 550.2553; HPLC purity: 98.36% (C-18 reverse phase, MeOH—H2O, 80:20).
