Reaction Steps
A mixture of [(2R)-6-bromo-2,3-dihydro-1,4-benzodioxin-2-yl]methanol (0.54 g, 2.05 mmol) (which can be prepared as in Biorg. Med. Chem. 2007, 15, 4048.), 6-chloro-5-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-1H-indole (0.52 g, 4.06 mmol) in DMF (4 mL) and dioxane (4 mL) was stirred at room temperature for 30 min. under N2. Pd(dppf)Cl2 (100 mg, 0.137 mmol) and 2 N potassium carbonate (10 mL, 20 mmol) was added. The resulting mixture was stirred for 30 min. at 90° C. under N2. TLC showed the reaction was complete. Water (50 mL) and methylene chloride (50 mL) was added. The aqueous layer was extracted with methylene chloride (30 mL×3). The combined organic layer was dried over sodium sulfate, filtered and evaporated to give the title compound (1 g) which was used in the next step without further purification.
