Reaction Steps

To a mixture of [1-(4-bromo-2-methoxyphenyl)cyclobutyl]methanol (180 mg, 0.660 mmol) in dioxane (10 mL) and water (4 mL) was added methyl 6-chloro-5-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-1H-indole-3-carboxylate (213 mg, 0.660 mmol), Pd (dppf)Cl2 (48 mg, 0.070 mmol) and potassium carbonate (273 mg, 2.00 mmol). The reaction mixture was purged with nitrogen for 3 minutes and stirred at 80° C. for 2 hours. The mixture was extracted with dichloromethane. The organic phases were combined, dried over sodium sulfate, filtered, and concentrated in vacuo to give the title compound (220 mg, 83%) as a brown solid. It was used for next step without further purification.
