Reaction Steps

Sodium hydride 60% in mineral oil (18 mg, 0.74 mmol) was added to a solution of 1H-1,2,4-Triazole (45 mg, 0.65 mmol) in DMF (10 mL) at room temperature. After stirring for 1 hour at room temperature, 7-bromo-6-(4-methoxybenzyl)-3-methyl-9-pentyl-6,9-dihydro-5H-[1,2,4]triazolo[4,3-a]purin-5-one (200 mg, 0.40 mmol) in DMF was added to above solution and the mixture was stirred overnight. The reaction was quenched with a drop of water and the reaction mixture was purified by pre LC-MS to give the desired product (53 mg, 27.2%) and its region-isomer 6-(4-methoxybenzyl)-3-methyl-9-pentyl-7-(1H-1,2,4-triazol-1-yl)-6,9-dihydro-5H-[1,2,4]triazolo[4,3-a]purin-5-one (53 mg, 27%). LCMS calculated for C22H26N9O2 (M+H): 448.2. found 448.2.
