Reaction Steps

To a solution of 8-((6-iodobenzo[d][1,3]dioxol-5-yl)thio)-9H-purin-6-amine (150 mg, 0.36 mmol) in 10 mL of dry DMF was added N-(3-bromopropyl)methanesulfonamide (300 mg, 1.4 mmol) and Cs2CO3 (190 mg, 0.58 mmol). The resulting mixture was stirred at a temperature of about 25° C. for 3 hrs, condensed under reduced pressure and purified by flash chromatography to provide compound WS34 as white solid (49 mg, 25% yield).
