Procedure

To a mixture of N-{9-methyl-6-morpholin-4-yl-8-[3-(tetrahydropyran-4-yl)azetidin-1-ylmethyl]-9H-purin-2-yl}benzene-1,2-diamine (0.234 g, 0.49 mmol) and 2,2-difluoropropionic acid (0.057 g, 0.51 mmol) and DIPEA (0.185 mL, 1.08 mL) in DMF (14 mL) was added HATU (0.223 g, 0.59 mmol) and the reaction mixture was stirred at room temperature for 24 h. The reaction mixture was concentrated in vacuo and the residue purified by flash chromatography (Si—PPC, MeOH:DCM, gradient 0:100 to 7.5:92.5). The solution was concentrated in vacuo, the residue was diluted in acetic acid (30 mL) and the reaction mixture was stirred at 90° C. for 18 h. The reaction mixture was concentrated in vacuo and the residue was purified by flash chromatography (Si—PPC, MeOH:DCM, 0:100 to 7.5:92.5) followed by reverse phase HPLC (Phenomenex Gemini 5u C18, 20 mM triethylamine in water on a gradient of acetonitrile 95:5 to 2:98) to give 468 as a white solid (0.063 g, 24%). LCMS (Method I): RT=3.34 min, [M+H]+ 553.3. 1H NMR (400 MHz, DMSO-d6): δ 7.84-7.82 (m, 1 H); 7.75-7.72 (m, 1 H); 7.42-7.36 (m, 2 H); 4.58 (dd, J=7.85, 6.0 Hz, 2 H); 4.40-4.00 (m, 4 H); 4.32 (t, J=6.0 Hz, 2 H); 3.78 (s, 3 H); 3.77 (s, 2 H); 3.77-3.73 (m, 4 H); 2.85 (d, J=11.1 Hz, 2 H); 2.68-2.66 (m, 1 H); 2.26 (t, J=19.02 Hz, 3H); 2.09 (t, J=11.1 Hz, 2 H); 1.57 (d, J=12.5 Hz, 3 H); 1.03 (d, J=12.5 Hz, 2 H)
