Reaction Steps

1-Bromo-2-methyl-4-(trifluoromethyl)benzene (1.144 g, 4.79 mmol), 3,4-bis(benzyloxy)-6-ethenylpyridazine (Intermediate 78; 1.27 g, 3.99 mmol), palladium(II) acetate (0.045 g, 0.199 mmol), triethylamine (10.56 ml, 76 mmol), tri-o-tolylphosphine (0.243 g, 0.798 mmol) and acetonitrile (8 ml) were combined. The reaction mixture was subjected to microwave irradiation at 120° C. for 30 minutes before being quenched with water and extracted into ethyl acetate. The combined organics were washed with brine, dried (MgSO4) and concentrated in vacuo to afford an orange gum. This was purified by column chromatography (silica, eluting with 0-30% ethyl acetate in petrol) to afford 3,4-bis(benzyloxy)-6-[(E)-2-[2-methyl-4-(trifluoromethyl)phenyl]ethenyl]pyridazine as a white solid (1.04 g, 55%).
