The three component condensation of an aldehyde, Substituted urea and 3-oxobutanamide in presence of catalytic amount of AlCl3 is disclosed for the synthesis of pyrimidine under solvent free microwave irradiation conditions. High yields are achieved even 1 g scale, while reaction times are considerably shortened compare to conventional method The antimicrobial activities of the pyrimidines (1a-t) are compared with those of known chosen standard drugs, viz. ampicillin, chloramphenicol, ciprofloxacin, norfloxacin and griseofulvin.
Key words: N-substituted, pyrimidines, AlCl3 catalyst, microwave irradiation, antimicrobial activity.
