실험 절차

4-(2-Benzyl-7-trifluoromethyl-2H-indazol-3-yl)-phenol (180 mg, 0.5 mmol), cesium carbonate (490 mg, 1.5 mmol), CuI (20 mg, 0.1 mmol) and 4-bromo-benzoic acid methyl ester (215 mg, 1.0 mmol) were dissolved in 3 ml of dry pyridine. The reaction mixture was run in microwave (Emory's Optimizer, Personal Chemistry) at 200° C. for 30 min. After cooling to room temperature, the reaction mixture was diluted with 1 M HCl (aq.) and the product extracted three times with CH2Cl2. Combined organic phases were dried and evaporated, and the crude material was purified with preparative HPLC using a gradient with an acidic mobile phase on an ACE-C8 column to afford 151 mg of analytically pure product.
