실험 절차

A solution of cyclohexanecarboxylic acid N′-[2-(2-bromo-4-fluoro-phenoxy)-acetyl]-N′-isopropyl-hydrazide (310 mg, 0.75 mmol) in DME (3 ml)/2M Na2CO3 (1.3 ml, 2.62 mmol) was treated 2-trifluoromethoxybenzeneboronic acid (231 mg, 1.12 mmol) and Pd[PPh3]4 (172 mg, 0.15 mmol) in a microwave oven at 150° C. for 10 min. The reaction mixture was partitioned between water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, filtered, and concentrated. The crude was purified first on a silica gel column with a 30-80% ethyl acetate/hexanes gradient to afford the product as a solid (232 mg, 63%). MS m/e 497.53 (M+H+)
