Reaction Steps
A mixture of 6-bromoindole (480 mg, 2.45 mmol), 4-(dihydroxyboryl)benzoic acid (406 mg, 2.45 mmol), Pd(dppf)Cl2.CH2Cl2 (10 Mg, 0.01 mmol), and 2M Na2CO3 (5.6 mL, 11.2 mmol) in a mixture of ethanol (4 mL) and DMF (7 mL) was heated to 100° C., stirred for 16 hours, filtered, and concentrated The concentrate was dissolved in ethyl acetate, washed sequentially with 1M H3PO4, water, and brine, dried (MgSO4), filtered, and concentrated. The concentrate was purified by flash column chromatography on silica gel with 5% methanol/dichloromethane to provide the desired product. MS (ESI(−)) m/e 236 (M−H)−.
