Imidazo(1,2-a)pyrimidine → 5H,6H,7H,8H-imidazo[1,2-a]pyrimidine

Participants

Reaction Steps

4.2 g imidazo[1,2-a]pyrimidine hydroperchlorate were heated for 8 h in an acetic acid solution with palladium on activated charcoal, with H2 fed in. Subsequent filtration, removal of the solvent and addition of diethyl ether yielded the 5,6,7,8-tetrahydro-imidazo[1,2-a]pyrimidine hydroacetate in the form of colorless crystals, which were recrystallized from ethanol.
