Procedure

tert-Butyl {1-[5-chloro-3-(1-isopropylazetidin-3-yl)-2-methoxy-4-methylphenyl]ethyl}carbamate (19 mg, 0.048 mmol) was treated with 4.0 M HCl in dioxane (60 μL, 0.24 mmol) in methylene chloride (50 μL) at room temperature for 2 hours. The resultant mixture was concentrated to dryness to give 1-[5-chloro-3-(1-isopropylazetidin-3-yl)-2-methoxy-4-methylphenyl]ethanamine dihydrochloride. A mixture of the HCl salt, 6-bromo-9-(tetrahydro-2H-pyran-2-yl)-9H-purine (20 mg, 0.072 mmol, from Example 108, Step 1) and DIPEA (42 μL, 0.24 mmol) in ethanol (0.3 mL) was heated at 100° C. overnight. The mixture was treated with 6.0 M HCl in water (80 μL, 0.5 mmol) at room temperature for 10 min and then purified on prep-LCMS (XBridge C18 Column, eluting with a gradient of acetonitrile in water with 0.05% trifluoroacetic acid, at flow rate of 30 mL/min) to afford the desired product as TFA salt. LCMS calculated for C21H28ClN6O (M+H)+: m/z=415.2. found: 415.1.
