Reaction Steps

To a solution of 7-(4-chlorobenzyl)-3-methyl-8-(propylthio)-1H-purine-2,6(3H,7H)-dione (124 mg, 0.34 mmol) in DMF (7 mL) was added 1-(2-bromoethyl)cyclopropanol (67.3 mg, 0.41 mmol, intermediate 46), followed by potassium carbonate (141 mg, 1.02 mmol). The reaction was stirred at 70° C. for 5 h. The reaction was cooled and partitioned between ethyl acetate and water. The organic phase was washed with brine, dried over sodium sulfate, filtered and concentrated to give a crude yellow oil product (100 mg, 66.9% yield). LCMS MH+ 449.
