실험 절차

To a solution of 8-((6-iodobenzo[d][1,3]dioxol-5-yl)thio)-9H-purin-6-amine (100 mg, 0.24 mmol) in 5 mL of dry DMF was added N-(2-bromoethyl)methanesulfonamide (150 mg, 0.7 mmol) and Cs2CO3 (150 mg, 0.46 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 WS35 as white solid (35 mg, 27% yield).
