Procedure

According to General Procedure I for Buchwald coupling, into a vial was added 1-((2-chloro-9-methyl-6-morpholino-8,9-dihydro-7H-purin-8-yl)methyl)-N,N-dimethylpiperidin-4-amine (0.044 g, 0.11 mmol), 2-ethyl-1H-benzo[d]imidazole (0.0171 g, 0.117 mmol), Xphos (0.00692 g, 0.0145 mmol), Tris(dibenzylideneacetone)dipalladium(0) (0.00696 g, 7.60E-6 mol), and Cesium Carbonate (0.0728 g, 0.223 mmol). The mixture was dissolved in N,N-Dimethylformamide (0.865 mL, 0.0112 mol). The reaction was heated at 145° C. under pressure for 30 minutes in a microwave reactor. The reaction mixture was filtered and concentrated. The crude was purified by reverse phase HPLC to give 306 (26.7 mg, 47%). [M+H]+=536.3.
