Pyridine → 1-(4-Fluorophenyl)-5-iodo-6-methylindazole

関与物質

反応手順

5-Iodo-6-methylindazole (1.3 g, 5.0 mmol), p-fluorobenzeneboronic acid (1.4 g, 10 mmol), anhydrous copper(II) acetate (1.4 g, 7.5 mmol) and pyridine (0.80 mL, 10 mmol) were stirred in dichloromethane (30 mL) overnight. Additional portions of p-fluorobenzeneboronic acid (0.47 g, 3.4 mmol), anhydrous copper(II) acetate (0.45 g, 2.5 mmol) and pyridine (0.27 mL, 3.4 mmol) were added. The mixture was filtered through celite after stirring for an additional night. The filtrate was concentrated and purified by column chromatography (SiO2, toluene) to give the subtitle compound (0.90 g, 51%) as a light orange powder.
