Abstract
Abstract Some new 2-aryl-3,7-dihydro-4 H -pyrrolo[2,3-d]pyrimidin-4-ones have been prepared through cyclocondensation of 2-amino-1 H -pyrrole-3-carboxamides with aromatic aldehydes followed by air oxidation in the presence of 3-methyl-1-(4-sulfonic acid)butylimidazolium hydrogen sulfate [(CH 2 ) 4 SO 3 HMIM][HSO 4 ], a Bronsted-acidic ionic liquid, as a green and reusable catalyst in solvent-free conditions.
