実験手順

A mixture of 8-azetidin-3-ylmethyl-2-(2-methylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine (131 mg, 0.31 mmol), acetic acid 1-chlorocarbonyl-1-methylethyl ester (45 μL, 0.31 mmol) and NEt3 (40 μL, 0.31 mmol) in THF (3 mL) was allowed to stir at r.t. for 16 h then concentrated in vacuo. The resulting residue was partitioned between DCM and H2O, the organic phase dried (Na2SO4) and concentrated in vacuo. The residue was purified by column chromatography (Si—PCC, MeOH:EtOAc, 0-10%) affording the title compound as a white solid (125 mg, 73%). LCMS (method H): RT 2.50 min [M+H]+ 547.5
