Procedure

8-Chloro-3-pentyl-7-(2-propen-1-yl)-1-[3-(1H-pyrazol-4-yl)propyl]-3,7-dihydro-1H-purine-2,6-dione (81 mg, 0.2 mmol) and sodium carbonate (85 mg, 0.8 mmol) were stirred in dry DMF (2 ml) with 2,4-difluorobenzyl bromide (166 mg, 0.8 mmol) at 45° C. for 18 h. The mixture was degassed and stirred with tetrakis(triphenylphosphine)palladium(0) (46 mg, 0.04 mmol) and morpholine (176 mg, 2 mmol) at rt for 6 h. The reaction was worked up and purified by aminopropyl SPE (5 g, washing with THF-MeOH (1:1) then neat MeOH, eluting with DCM-MeOH (1:1) with 5% added AcOH) to yield the title compound (37.7 mg) as a solid.
