実験手順

Palladium acetate (0.0018 g, 8.09 μmol), di-tert-butyl(2′,4′,6′-triisopropyl-3,6-dimethoxybiphenyl-2-yl)phosphine (0.0086 g, 0.018 mmol) and water (0.6 μL, 0.032 mmol) were charged to a 40-mL reaction vial inside an inert atmosphere glove box. tert-Amyl alcohol (1.0 mL) was added, and the contents were heated to 80° C. and stirred at this temperature for 15 minutes. The reaction mixture was cooled down to room temperature. Potassium phosphate tribasic (0.094 g, 0.445 mmol), 6-(3-tert-butyl-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-2-methoxyphenyl)naphthalen-2-yl methanesulfonate (0.2 g, 0.404 mmol), methanesulfonamide (0.046 g, 0.485 mmol) and tert-amyl alcohol (1.5 mL) were added to the 40-mL reaction vial. The reaction temperature was raised to 110° C., and the contents were stirred for 14 hours. HPLC analysis of the reaction mixture showed that the titled compound was formed in 5 area % at 210 nm.
