Procedure
To 2-(2-hydroxyethylamino)-7-(4-methoxybenzyl)-1-((4-methylquinazolin-2-yl)methyl)-1H-purin-6(7H)-one 12 (1.68 g, 3.56 mmol) in DCM (66 ml) was added Et3N (1.50 ml, 10.7 mmol) and MsCl (0.55 ml, 7.1 mmol). The mixture was stirred at room temperature for 3 hours. The reaction mixture was extracted with DCM, washed with water, NaHCO3 and brine, dried (MgSO4) and concentrated. The crude product was purified by flash chromatography (MeOH/DCM) to afford 3-(4-methoxybenzyl)-5-((4-methylquinazolin-2-yl)methyl)-7,8-dihydro-3H-imidazo[2,1-b]purin-4(5H)-one 13. 1H NMR S 8.03 (d, J=7.81, 1H), 7.87 (d, J=7.81, 1H), 7.78 (t, J=7.03, 1H), 7.55 (t, J=7.03, 1H), 7.46 (s, 1H), 7.28 (d, J=8.59, 2H), 6.85 (d, J=8.59, 2H), 5.60 (s, 2H), 5.38 (s, 2H), 4.20 (d, J=9.37, 2H), 3.78 (d, J=9.37, 2H), 3.78 (s, 3H).
