(R)-2-(2-bromo-1H-imidazol-1-yl)-8-cyclopentyl-7-ethyl-5-methyl-7,8-dihydropteridin-6(5H)-one (Example 65, 0.11 g, 0.271 mmol), oxazolidin-2-one (35 mg, 0.406 mmol), CuI (10 mg, 0.054 mmol), trans-1,2-bis(methylamino)cyclohexane (15 mg, 0.108 mmol) and K2CO3 (74 mg, 0.542 mmol) were dissolved in 1 mL of dioxane in a screw cap vial and a stream of nitrogen was bubbled through the mixture for 2 minutes. The resulting solution was stirred at 110° C. for 18 h. The reaction mixture filtered and concentrated, then purified by preparative HPLC to give the title compound (7.1 mg). LCMS: 412.2 m/z (M+H)+; ret. Time: 3.24 min (Analytical Method A).
