実験手順
A mixture of 2-amino-6-chloro-9-(2-hydroxyethyl)-7H-purin-8-one obtained in step 2 (13 g, 56.7 mmol), K2CO3 (11.5 g, 84 mmol), methyl iodide (12 g, 85.15 mmol) and DMF (130 ml) were stirred at 25-30° C. for 16 hours. The reaction mixture was concentrated and purified by column chromatography using 60-120 silica gel and 4% methanol in DCM as an eluent to obtain 2-amino-6-chloro-9-(2-hydroxyethyl)-7-methyl-purin-8-one (8 g, 58%) as an off white solid.
