실험 절차

A vessel containing 3,4-bis(benzyloxy)-6-ethenylpyridazine (Intermediate 78, 1.09 g, 3.42 mmol), tris-(2-methylphenyl)phosphane (0.208 g, 0.685 mmol), 2-fluoro-4-iodo-1-(trifluoromethyl)benzene (1.191 g, 4.11 mmol) and palladium(II) acetate (0.038 g, 0.171 mmol) was evacuated and acetonitrile (10 ml) and triethylamine (9.07 ml, 65.1 mmol) were added in vacuo and then the mixture was flushed with nitrogen. The reaction was then heated in the microwave at 80° C. for 4 hours and, upon cooling, was diluted with dichloromethane and washed with saturated aqueous ammonium chloride solution. The organics were dried (MgSO4), filtered and solvent removed in vacuo to give a brown oil which was purified by column chromatography (silica, eluting with 30-100% dichloromethane in petrol) to yield 3,4-bis(benzyloxy)-6-[(E)-2-[3-fluoro-4-(trifluoromethyl)phenyl]ethenyl]pyridazine (1.1 g, 2.29 mmol, 67% yield).
