Reaction Steps

To a solution of 2-amino-9-((2R,3S,4R,5S)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-1H-purin-6(9H)-one (14 g, 49.47 mmol) in DMSO (50 mL) was added (bromomethyl)benzene (10 g, 59.36 mmol). The mixture was stirred at 50° C. overnight. Then the mixture was cooled to room temperature and HCl (50 mL, 10% w.w) was added and the mixture was stirred at 70° C. for 2 h. The reaction was cooled to room temperature, filtered and the filter cake was washed with water and ethanol and dried under vacuum to give 2-amino-7-benzyl-1H-purin-6(7H)-one (10 g, 74.2% yield) as grey solid. LCMS retention time 0.529 min; LCMS MH+ 242.
