Reaction Steps

To a solution of [2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purin-8-yl]piperidin-4-ylmethanone (47 mg, 0.10 mmol) and NEt3 (27 μL, 0.20 mmol) in DCM (5 mL) was added cyclopropane carbonyl 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 30-70%) affording 864 (13 mg, 25%). LCMS (method I): RT 4.06 min, [M+H]+ 543.3. 1H NMR (CDCl3, 400 MHz): δ 8.07-8.06 (1 H, m), 7.89-7.82 (1 H, m), 7.40-7.30 (2 H, m), 4.70-4.56 (3 H, m), 4.39-4.28 (1 H, m), 4.13 (3 H, s), 3.93-3.90 (6 H, m), 3.52-3.27 (3 H, m), 2.94-2.80 (1 H, m), 2.08-1.97 (2 H, m), 1.97-1.57 (4 H, m), 1.50 (3 H, t, J=7.40 Hz), 1.04-0.98 (2 H, m), 0.79-0.78 (2 H, m)
