Procedure

To a solution of (R)-2-(2-amino-4-(4-fluorophenyl)thiazol-5-yl)-7-ethyl-8-isopropyl-5-methyl-7,8-dihydropteridin-6(5H)-one (Example 318, 0.14 g, 0.324 mmol) in 1.5 mL anhydrous THF, isoamyl nitrite (0.1 mL, 0.751 mmol) was added. The reaction mixture was place in an oil bath set at 85° C. for 2 h and then concentrated and purified by preparative HPLC. LCMS: 412.2 m/z (M+H)+; ret. Time: 4.84 min (Analytical Method A).
