Reaction Steps
The 4-[(phenylmethyl)oxy]-1H-indazole (D1) (543 mg, 1.65 mmol), the [4-(methyloxy)phenyl]boronic acid (500 mg, 3.29 mmol), copper (II) acetate (448 mg, 2.47 mmol), powdered molecular sieves (400 mg) and pyridine (0.27 mL, 3.29 mmol) in DCM (75 mL) were stirred at room temperature in the presence of air. After 4 hours the mixture was filtered through a pad of celite and washed with water. The aqueous was re-extracted with DCM and the combined organics were washed with brine and dried over MgSO4. The crude (880 mg) was purified by flash chromatography (Biotage SP4) with a gradient of Et2O (0 to 30%) in hexane to afford 115 mg of title compound (D32).
