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 1-chloro-4-(chloromethyl)benzene (10 g, 62.16 mmol). The reaction was stirred at 50° C. overnight. The mixture was cooled to room temperature and HCl (50 mL, 10% w.w) was added. The reaction was stirred at 70° C. for 2 h. The reaction was cooled and the precipitate was collected and washed with water and ethanol. The product was dried under vacuum to give 2-amino-7-(4-chlorobenzyl)-1H-purin-6(7H)-one (10 g, 74.1% yield) as grey solid. LCMS retention time 0.529 min; LCMS MH+ 276.
