Reaction Steps
A mixture of methyl 6-chloro-5-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-1H-indole-3-carboxylate (100 mg, 0.311 mmol), 1-[2-(4-bromophenyl)azetidin-1-yl]ethanone (100 mg, 0.373 mmol), 2.0 M aqueous potassium carbonate (0.50 mL, 1.0 mmol), and Pd(dppf)Cl2 (30 mg, 0.03 mmol) in toluene/ethanol (1.44 mL/0.48 mL) was stirred at 110° C. for 2.5 hours. The mixture was poured into ethyl acetate and washed with water. The organic phase was dried over sodium sulfate, filtered, and concentrated to give a residue. This was purified by preparative TLC to give the title compound (40 mg, 51% yield) as a white solid.
