Reaction Steps

A solution of 3-pyridin-2-yl-7-(trifluoromethyl)-2H-indazole (0.2633 g, 1 mmol), 2-methylphenylboronic acid (0.271 g, 2 mmol, copper(II)acetate (0.181 g, 1 mmol) and pyridine (0.161 mL, 2 mmol) in 20 mL of methylene chloride was stirred at ambient temperature for 2 hours. The reaction mixture was concentrated in vacuo and purified by flash chromatography (silica gel 60, methylene chloride-ethyl acetate, 3:1) to give the title compound (0.08 g).
