Participants

Reaction Steps

Carbonyldiimidazole (0.93 g) was added to a solution of N2-(2,4-dimethoxybenzyl)-N4-(2,6-difluorobenzyl)pyrimidine-2,4,5-triamine (54) in THF (20 mL) and the resultant mixture stirred at RT overnight, then the solvents were removed under reduced pressure and the taken up in EtOAc and washed trice with water. The organics were dried, filtered and evaporated and purified via column chromatography, elution with 2.5 and 4% MeOH/DCM, to yield 2-(2,4-Dimethoxybenzylamino)-9-(2,6-difluorobenzyl)-7H-purin-8(9H)-one (55) (0.58 g), MH+=428.
