Twelve new 4-(1H-indol-3-yl)-6-phenyl-1,2,3,4-tetrahydropyrimidin-2-ones/thiones (7-18) have been synthesized by reacting 1-aryl-3-(1H-indol-3-yl)-2-propen-1-one with urea and thiourea in ethanolic potassium hydroxide. Their structures have been confirmed by IR, 1H NMR and mass spectral data. The compounds were tested for their anti-inflammatory activity.
