Procedure

N1-(8-((4-tert-butylpiperazin-1-yl)methyl)-6-morpholino-9-(tetrahydro-2H-pyran-2-yl)-9H-purin-2-yl)benzene-1,2-diamine (0.085 g, 0.15 mmol) and 2,2-difluoropropanoic acid (0.019 g, 0.17 mmol) were dissolved in N,N-dimethylformamide (2 mL, 0.02 mol). N,N-Diisopropylethylamine (0.054 mL, 0.31 mmol) was added. The resulting solution was cooled at 0° C. for 20 minutes. N,N,N′N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium hexafluorophosphate (0.070 g, 0.00018 mol) was added and the reaction stirred overnight at room temperature. The reaction mixture was concentrated to dryness. Acetic acid (3.0 mL, 0.053 mol) was added to the crude residue and the reaction mixture was heated at 90° C. for 18 hours. The reaction mixture was cooled, filtered and concentrated to dryness. The crude was purified by reverse phase HPLC to give 457 (15.3 mg, 18%). [M+H]+=540.3
