Versuchsvorschrift

To a solution of 6-chloro-8-phenyl-7H-purine (0.200 g, 0.000867 mol) (Example 109, step a) in DMF (8.0 mL, 0.10 mol) was added sodium hydride (0.025 g, 0.0010 mol). The mixture was stirred for 20 minutes and to this was added methyl iodide (0.065 mL, 0.0010 mol) and the mixture was stirred for 2 hours. The reaction was quenched by addition of saturated aqueous NH4Cl, and the mixture was extracted with ethyl acetate, washed with water, brine, dried (Na2SO4), filtered and concentrated. The residue was purified by flash chromatography (3 to 10% acetone/toluene) to obtain 145 mg (68%).
