Some new 2-aryl-3,7-dihydro-4H-pyrrolo[2,3-d]pyrimidin-4-ones have been prepared through cyclocondensation of 2-amino 1H-pyrrole-3-carboxamides with aromatic aldehydes followed by air oxidation in the presence of 3-methyl-l-(4-sulfonic acid)butylimidazolium hydrogen sulfate [(CH₂)₄SO₃HMIMJ[HSO₄], a Brφnsted-acidic ionic liquid, as a green and reusable catalyst in solvent-free conditions.
- Pyrrolo[2,3-d]pyrimidin-4-ones,
- 7-Deazapurines,
- Aromatic aldehydes,
- Brφnsted-acidic ionic liquids
