Procedure

To a mixture of 2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine-8-carboxylic acid (117 mg, 0.26 mmol), 1-methanesulfonyl-3,3-dimethylpiperazine (51 mg, 0.26 mmol) and HATU (100 mg, 0.26 mmol) in DMF (1 mL) was added NEt3 (720 μL, 5.18 mmol). The resulting mixture was allowed to stir at r.t. for 16 h then partitioned between EtOAc and H2O. The organic phase was dried (MgSO4) and concentrated in vacuo and the resulting residue was purified by column chromatography (Si—PCC, MeOH:EtOAc, 0-5%). The resulting solid was recrystallised from EtOAc and Et2O affording 715 (50 mg, 33%). LCMS (method I): RT 3.68 min, [M+H]+ 582.2. 1H NMR (CDCl3, 400 MHz): δ 8.03-8.03 (1 H, m), 7.76-7.75 (1 H, m), 7.31-7.27 (2 H, m), 4.35 (4 H, brd s), 4.03 (2 H, t, J=5.39 Hz), 3.95 (3 H, s), 3.87 (4 H, t, J=4.70 Hz), 3.50 (2 H, t, J=5.40 Hz), 3.37 (2 H, q, J=7.47 Hz), 3.31 (2 H, s), 2.90 (3 H, s), 1.68 (6 H, s), 1.45 (3 H, t, J=7.47 Hz)
