Procedure
To a mixture of [(S)-1-(7-cyclopropyl-6-fluoro-1-phenyl-1H-benzoimidazol-2-yl)ethyl]-[9-(tetrahydropyran-2-yl)-9H-purin-6-yl]amine (20 mg, 0.04 mmol) in MeOH (2 mL) was added 4N HCl in dioxane (0.25 mL) and the reaction mixture stirred at RT for 30 min. The volatiles were removed under reduced pressure and the resulting residue purified by reverse phase HPLC (Phenomenex Gemini 5 μm C18 on a 20 min gradient 10-90%, 0.1% HCO2H in acetonitrile/water) to afford 198 (8 mg, 48%). LCMS (Method K): RT 3.74 and 3.81 min [M+H]+ 414.1. 1H NMR (DMSO-d6, 400 MHz): δ 12.89 (1H, br s), 8.19-7.97 (2H, m), 7.90-7.30 (7H, m), 7.04-6.95 (1H, dd, J=11.67, 8.76 Hz), 5.29 (1H, br s), 1.52 (3H, d, J=6.81 Hz), 1.28-1.18 (1H, m), 0.43-0.29 (2H, m), 0.25-0.08 (2H, m)
