Reaction Steps
A mixture of 2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-8-piperidin-4-ylmethyl-9H-purine (230 mg, 0.50 mmol), cyclopropyl carbonyl chloride (50 μL, 0.55 mmol) and NEt3 (140 μL, 1.00 mmol) in DCM (10 mL) was allowed to stir at r.t. for 5 h then concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, MeOH:DCM, 0-5%) then further purified by reverse phase HPLC (Phenomenex Gemini 5 μm C18, 20 mM triethylamine in water on a gradient of acetonitrile 40-98%) affording 852 as a white solid (46 mg, 17%). LCMS (method I): RT 3.59 min, [M+H]+ 529.4. 1H NMR (DMSO, 400 MHz): δ 8.03-7.99 (1 H, m), 7.64-7.63 (1 H, m), 7.25-7.24 (2 H, m), 4.45-4.10 (6 H, m), 3.77-3.75 (6 H, m), 3.27-3.24 (3 H, m), 3.16-3.00 (1 H, m), 2.86 (2 H, d, J=7.07 Hz), 2.64-2.47 (1 H, m), 2.20-2.08 (1 H, m), 2.01-1.93 (1 H, m), 1.79-1.71 (2 H, m), 1.33 (3 H, t, J=7.43 Hz), 1.30-1.07 (2 H, m), 0.74-0.66 (4 H, m)
