Reaction Steps

To a mixture of 3-(4-bromo-2-methoxyphenoxy)propan-1-ol (97 mg, 0.37 mmol), methyl 6-chloro-5-(5,5-dimethyl-1,3,2-dioxaborinan-2-yl)-1H-indole-3-carboxylate (100 mg, 0.31 mmol) and potassium carbonate (128 mg, 0.93 mmol) in toluene/EtOH (5 mL, 3:1) and water (1 ml) was added Pd(dppf)Cl2 (22 mg, 0.031 mmol). The mixture was degassed and purged with nitrogen for 5 minutes, then allowed to heat to 110° C. and stirred for 30 minutes. The reaction mixture was concentrated in vacuo to give a brown residue. The residue was purification by flash chromatography to give the title compound (92 mg, 76% yield) as a pale solid. 1H NMR (400 MHz, CD3OD) δ 8.01 (s, 1H), 8.00 (s, 1H), 7.58 (s, 1H), 7.03 (m, 2H), 7.00 (m, 1H), 4.18 (m, 2H), 3.87 (s, 3H), 3.80 (m, 2H), 3.37 (s, 3H), 2.05 (m, 2H).
