Procedure

A mixture of 8-(2,2-dimethylpiperazin-1-ylmethyl)-2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine (120 mg, 0.25 mmol), 2-chloroacetamide (50 mg, 0.54 mmol) and NEt3 (50 μL, 0.36 mmol) in DCM (5 mL) was allowed to stir at r.t. for 5 h before further 2-chloroacetamide (100 mg, 1.07 mmol) and NEt3 (100 μL, 0.72 mmol) was added. The resulting mixture was allowed to stir for 84 h then 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 column chromatography (Si—PCC, MeOH:EtOAc, 0-5%) affording 717 (65 mg, 49%). LCMS (method I): RT 2.54 min, [M+H]+ 547.2. 1H NMR (CDCl3, 400 MHz): δ 8.02-7.99 (1 H, m), 7.77-7.74 (1 H, m), 7.32-7.22 (2 H, m), 6.95 (1 H, brd s), 5.43 (1 H, brd s), 4.34 (4 H, brd s), 3.90 (3 H, s), 3.86 (6 H, t, J=4.76 Hz), 3.35 (2 H, q, J=7.48 Hz), 2.96 (2 H, s), 2.62-2.45 (4 H, m), 2.38 (2 H, s), 1.45 (3 H, t, J=7.48 Hz), 1.25 (6 H, s)
