Procedure
To a solution of [2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purin-8-yl]piperidin-4-ylmethanone and NEt3 (27 μL, 0.20 mmol) in DCM (5 mL) was added isobutyryl chloride (10 μL, 0.12 mmol) and the resulting mixture stirred at r.t. for 3 h. The reaction mixture was quenched with H2O and extracted with DCM. The combined organic phases were dried (MgSO4) and concentrated in vacuo and the resulting residue loaded onto an Isolute® SCX-2 cartridge which was washed with MeOH and the product eluted with 2M NH3/MeOH. The resulting residue was purified by reverse phase HPLC (Phenomenex Gemini 5 μm C18, 0.1% NH4OH in water on a gradient acetonitrile 40-70%) affording 863 (7 mg, 13%). LCMS (method I): RT 4.19 min, [M+H]+ 545.3. 1H NMR (CDCl3, 400 MHz): δ 8.06-8.05 (1 H, m), 7.88-7.81 (1 H, m), 7.39-7.31 (2 H, m), 4.75-4.63 (2 H, m), 4.14-4.02 (5 H, m), 3.93-3.91 (5 H, m), 3.51-3.40 (2 H, m), 3.31-3.40 (1 H, m), 2.84-2.82 (2 H, m), 2.08-1.96 (2 H, m), 1.89-1.62 (4 H, m), 1.49 (3 H, t, J=7.43 Hz), 1.20-1.12 (6 H, m)
