実験手順

A suspension of Example 149c (0.150 g, 0.362 mmol), 2,6-dichloro-4-iodopyridine (0.099 g, 0.362 mmol), dichlorobis(triphenylphosphine)palladium(II) (10.17 mg, 0.014 mmol) and 1M sodium carbonate (0.290 mL, 0.290 mmol) in dimethoxyethane/EtOH/water (7:2:3, 2.5 mL) was degassed and heated at 80° C. overnight. After cooling, the suspension was diluted with water and extracted with EtOAc (2×). The suspension in the aq. layer was filtered, washed with water, and dried to give 88.0 mg of the title compound
