Procedure

A mixture of 8-bromomethyl-2-(2-ethylbenzoimidazol-1-yl)-9-methyl-6-morpholin-4-yl-9H-purine hydrobromide (200 mg, 0.37 mmol), (3S,5R)-1-methanesulfonyl-3,5-dimethylpiperazine (88 mg, 0.46 mmol) and K2CO3 (150 mg, 1.09 mmol) in DMF (1 mL) was allowed to stir at r.t. for 24 h. The reaction mixture was partitioned between EtOAc and H2O, the organic phase dried (MgSO4) and concentrated in vacuo. The resulting residue was purified by column chromatography (Si-PCC, MeOH:EtOAc, 0-10%) followed by recrystallisation from EtOAc affording 737 (57 mg, 28%). LCMS (method I): RT 3.05 min, [M+H]+ 568.2. 1H NMR (CDCl3, 400 MHz): δ 8.02-7.98 (1 H, m), 7.76-7.75 (1 H, m), 7.26-7.25 (2 H, m), 4.34 (4 H, s), 4.18 (2 H, s), 3.87 (4 H, t, J=4.70 Hz), 3.84 (3 H, s), 3.54-3.51 (2 H, m), 3.35 (2 H, q, J=7.48 Hz), 3.29-3.23 (2 H, m), 2.80 (3 H, s), 2.68-2.66 (2 H, m), 1.45 (3 H, dd, J=7.69, 7.26 Hz), 1.17 (6 H, d, J=6.36 Hz)
