Reaction Steps

A solution of tert-butanol (20.0 mL), DCE (20.0 mL) and DIEA (3.13 mL, 18.0 mmol) was treated with C8 (5.60 g, 15.0 mmol) and B5 (5.02 g, 15.0 mmol), and the resulting mixture was stirred at 80° C. under an atmosphere of nitrogen for 16 hours. The mixture was cooled to 25° C. and concentrated. The resultant residue was partitioned between EtOAc and 1 N sodium hydroxide, and the organic phase was collected. The aqueous layer was extracted with EtOAc, and the combined organic phases were dried over MgSO4 and filtered. The resultant filtrate was concentrated under reduced pressure, and the resultant residue was triturated with hot EtOAc to provide 9 as a white solid. Yield: 7.83 grams, 95%. LC/MS (standard) 250=3.0 min., m/z 553.6 (MH+).
