Procedure

N,N-Dimethylformamide (60 ml), isobutyl bromide (2 ml, 18 mmol), and potassium carbonate (3 g) were added to 2-chloro-6-morpholin-4-yl-9H-purine (5 g, 17 mmol) and the resulting mixture was stirred at 80° C. for 5 hours. The reaction mixture was cooled and partitioned with ethyl acetate and water and the organic layer was dried over magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound (5.2 g, 100%) as a pale yellow oil.
