Reaction Steps

9-Cyclopentyl-N2-(6-methoxypyridin-3-yl)-N8-(2,4,6-trifluorophenyl)-9H-purine-2,8-diamine (0.350 g, 0.769 mmol) was dissolved in 30% HBr/acetic acid in a sealed tube and heated to 80° C. for 16 hours. Product confirmed by LC-MS. The solution was partitioned between 1.75 M potassium carbonate and ethyl acetate (3×). The organics were combined, dried over magnesium sulfate, filtered and solvent removed under reduced pressure. The resultant solid was purified via preparative HPLC (5-55% acetonitrile/water, 20 mL/min.) to afford the title compound (0.212 g, 34%). ES-MS (m/z) 442 [M+1]+. Melting point 257-260° C.
