Reaction Steps

To a solution of 8-bromo-7-(4-chlorobenzyl)-3-methyl-1-(3-(tetrahydro-2H-pyran-2-yloxy)propyl)-1H-purine-2,6(3H,7H)-dione (0.28 g, 0.4 mmol, intermediate 14) in DMSO (10 mL) was added sodium azide (65 mg, 1 mmol). The reaction was heated at 65° C. for 2.5 h. The mixture was cooled and partitioned between ethyl acetate and water. The combined organic layer was dried over sodium sulfate, filtered and concentrated to give a crude product which was used without purification. LCMS retention time 1.800 min; LCMS MH+-THP 390.
