Reaction Conditions

Reaction Steps

To a solution of commercially available 2-chloro-9H-purin-6-amine (1 equiv.) in DMF (0.50 M) was added potassium carbonate (1.2 equiv.) and diethyl 4-(bromomethyl)benzylphosphonate (1 equiv.) (described in ref. 88, Ex 25 Step 1). The reaction mixture was then heated to 60° C. for 5 h. At this point the reaction mixture was allowed to cool to room temperature and the volatiles were removed in vacuo. The resulting residue was purified by a COMBIFLASH™ system (ISCO) using a gradient of 0-5% MeOH/DCM to provide the title compound (18%) as a solid.
