Versuchsvorschrift

(R)-2-(2-bromo-1H-imidazol-1-yl)-8-cyclopentyl-7-ethyl-5-methyl-7,8-dihydropteridin-6(5H)-one (Example 65, 0.15 g, 0.37 mmol), 4-(methylsulfonyl)phenylboronic acid (0.148 g, 0.74 mmol), aqueous sodium hydroxide (240 μL of 3N) and Pd(PPh3)4 (42 mg, 0.037 mmol) were dissolved in 1.2 mL of DME/H2O (5/1, v/v) and a stream of nitrogen was bubbled through the mixture for 2 minutes. The resulting solution was stirred at 90° C. for 18 h. The reaction mixture was diluted with brine, extracted with EtOAc, dried with Na2SO4 then purified by silica gel column chromatography and preparative HPLC to give to give the title compound (3.8 mg). LCMS: 481.2 m/z (M+H)+; ret. Time: 6.19 min (Analytical Method C).
