Reaction Steps
To the mixture of 4-pentyl-1,4-dihydro-9H-[1,2,4]triazolo[1,5-a]purin-9-one (19 mg, 0.077 mmol) in tetrahydrofuran (10 mL) was added N-bromosuccinimide (20 mg, 0.12 mol) at rt. The mixture was stirred at 70° C. for 1 hour. The mixture was concentrated and purified by preparative LCMS to yield the desired product (3.10 mg, 12.4%). LCMS calculated for C11H14BrN6O(M+H): 325.0; found: 325.0, 327.0.
