Reaction Steps

A solution of 1-[2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purin-8-yl]-1-piperidin-4-ylethanol and NEt3 (74 μL, 0.53 mmol) in DCM (5 mL) was cooled to −78° before the addition of cyclopropane carbonyl chloride (18 μL, 0.20 mmol). The resulting mixture was stirred for 15 min then quenched with H2O and extracted with DCM. The combined organics were dried (phase separator) and concentrated in vacuo. The resulting residue was purified by reverse phase HPLC (Phenomenex Gemini 5 μm C18, 0.1% NH4OH in water on a gradient acetonitrile 10-70%) affording 865 as a white solid (44 mg, 44%). LCMS (method I): RT 3.51 min, [M+H]+ 559.4. 1H NMR (CDCl3, 400 MHz): δ 8.01-8.00 (1 H, m), 7.80 (1 H, d, J=7.13 Hz), 7.33-7.28 (2 H, m), 4.71 (1 H, brd s), 4.32 (4 H, brd s), 3.98 (3 H, s), 3.87 (4 H, t, J=4.69 Hz), 3.40 (2 H, q, J=7.47 Hz), 3.14-2.98 (1 H, m), 2.60-2.43 (1 H, m), 2.20-2.09 (1 H, m), 1.86-1.65 (6 H, m), 1.62-1.36 (3 H, m), 1.47 (3 H, t, J=7.47 Hz), 1.00-0.93 (2 H, m), 0.75-0.74 (2 H, m)
