実験手順

A suspension of bis(triphenylphosphine)palladium(II) chloride (70.3 mg, 0.1 mmol) and copper(I) iodide (19.1 mg, 0.1 mmol) in anhydrous THF (12 mL), was purged with Ar for 10 mins at rt. The suspension was treated with triethylamine (0.42 mL, 3.0 mmol), and 1-chloro-4-(4-ethynylphenoxy)-2-(trifluoromethyl)benzene (446 mg, 1.5 mmol) was added under an Ar atmosphere, which produced a dark amber color. After 5 mins, 8-chloro-1-methyl-3,4-dihydro-1H-pyrimido[1,6-a]pyrimidin-6(2H)-one (100 mg, 0.5 mmol) was added, and stirred for 2 h at 50° C. The reaction mixture was diluted with EtOAc, washed with water, and then concentrated. The residue was purified by MDAP to afford the title compound (30 mg) as a pale yellow solid.
