실험 절차

Add bis(triphenylphosphine)palladium (II) dichloride (64 mg, 0.091 mmol), copper (I) iodide (35 mg, 0.19 mmol), and 3-ethynyl-5-methoxypyridine, (prepared as described in PREPARATION 10), (250 mg, 1.9 mmol) to a solution of 2-fluoro-5-iodo-N-methylbenzamide, (prepared as described in PREPARATION 39), (0.63 g, 2.3 mmol) in triethylamine (3.8 mL, 27.3 mmol) and heat at 60° C. for 16 h. Cool to room temperature and concentrate. Purify by silica gel chromatography, eluting with 100:0 to 10:90 dichloromethane:ethyl acetate, followed by a second silica gel chromatography eluting with 50:50 to 75:25 ethyl acetate:hexanes, to give the title compound as a white solid (390 mg, 73%).
