Procedure
To a mixture of 2-(2-cyclopropylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine-8-carboxylic acid (500 mg, 1.19 mmol), 2-chloro-1-methylpyridinium iodide (729 mg, 2.86 mmol) and DIPEA (500 μL, 2.87 mmol) in DMF (10 mL) was added 4-azetidin-3-ylmorpholine (288 mg, 2.0 mmol) and the resulting mixture allowed to stir at r.t for 18 h. The reaction mixture was concentrated in vacuo and the resulting residue dissolved in EtOAc which was washed with H2O and brine, then dried (MgSO4) and concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, MeOH:EtOAc, 0-5%) affording 799 as a cream solid (290 mg, 45%). LCMS (method G): RT 5.90 min, [M+H]+ 544.5. 1H NMR (CDCl3, 400 MHz): δ 7.99-7.99 (1 H, m), 7.67-7.67 (1 H, m), 7.28-7.20 (2 H, m), 4.73-4.72 (1 H, m), 4.70-4.00 (4 H, brd s), 4.53-4.51 (1 H, m), 4.29-4.21 (1 H, m), 4.18-4.08 (4 H, m), 3.87 (4 H, t, J=4.67 Hz), 3.78 (4 H, t, J=4.60 Hz), 3.30-3.30 (1 H, m), 2.88-2.88 (1 H, m), 2.47-2.45 (4 H, m), 1.35-1.34 (2 H, m), 1.06-1.05 (2 H, m)
