Reaction Steps

To a solution of diethyl 4-((6-amino-8-bromo-2-(2-methoxyethoxy)-9H-purin-9-yl)methyl)benzylphosphonate in methanol (0.10 M) was added sodium methoxide (20 equiv.). The reaction mixture was then allowed to stir at 70° C. for 18 h. At this point the reaction mixture was allowed to cool to room temperature and then quenched by the addition of ammonium chloride. The mixture was then diluted with DCM, transferred to a separatory funnel and washed with DCM three times. The combined organic layers were then dried over anhydrous Na2SO4 and the volatiles were removed in vacuo. The resulting solid compound (38%) was carried onto the next step without further purification.
