Procedure

To a solution of 7-bromo-6-(4-methoxybenzyl)-3-methyl-9-pentyl-6,9-dihydro-5H-[1,2,4]triazolo[4,3-a]purin-5-one (100 mg, 0.3 mmol), 1-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (92 mg, 0.44 mmol) and sat. sodium carbonate (100 mg, 0.9 mmol) in toluene (20 mL, 0.2 mol) was added tetrakis(triphenylphosphine)palladium(0) (20 mg, 0.01 mmol) under N2 at room temperature. The mixture was heated to reflux overnight. The mixture was stripped down and purified by preparative LC-MS to yield the desired product (50 mg, 37%). LCMS calculated for C24H29N8O2 (M+H): 461.2. found 461.2.
