Tris(dibenzylideneacetone)dipalladium(0) (0.0026 g, 2.80 μmol), di-tert-butyl(2′,4′,6′-triisopropyl-3,6-dimethoxybiphenyl-2-yl)phosphine (0.0033 g, 6.72 μmol) and milled potassium phosphate tribasic (0.131 g, 0.616 mmol) were charged to a 40-mL reaction vial inside an inert atmosphere glove box. 2-Methyltetrahydrofuran (1.5 mL) was added, the vial was capped, and the contents were heated to 80° C. and stirred at this temperature for 30 minutes. The reaction mixture was cooled down to room temperature. 6-(3-tert-Butyl-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-2-methoxyphenyl)naphthalen-2-yl 1,1,2,2-tetrafluoro-2-(perfluoroethoxy)ethanesulfonate (0.4 g, 0.560 mmol, Example 3-7, compound (5f)), methanesulfonamide (0.064 g, 0.672 mmol) and ethyl acetate (3 mL) were added to the 40-mL reaction vial. The temperature of the closed vial was raised to 90° C. and the contents were magnetically stirred for 16 hours. HPLC analysis of the reaction mixture showed that the product was formed in 97 area % at 210 nm.
