Procedure

Triethylamine (0.510 mL, 3.66 mmol) and C9 (0.333 g, 1.58 mmol) were added to a solution of C6 (0.360 g, 1.22 mmol) in dichloromethane (10 mL), and the reaction mixture was heated at 40° C. for 18 hours. The mixture was then washed with saturated aqueous sodium chloride solution, dried over magnesium sulfate, filtered, and concentrated in vacuo. Purification was effected first via silica gel chromatography (Gradient: 0% to 100% ethyl acetate in heptane), then by reversed phase HPLC (Column: Phenomenex Gemini C18, 5 μm; Mobile phase A: 0.1% ammonium hydroxide in water; Mobile phase B: 0.1% ammonium hydroxide in methanol; Gradient: 5% to 100% B). The product was obtained as a solid. Yield: 202 mg, 0.556 mmol, 46%.
