A series of 2,3,3a,4‐tetrahydro‐3a‐methylpyrrolo[1,2‐a]quinazolin‐5(1H)‐one derivatives were synthesized by a reaction of 2‐aminobenzamide and 5‐chloropentan‐2‐one at 80 °C catalyzed by iodine in ionicliquid of [BMIm]Br. Compared with the other methods, this novel method has the advantages of milder reaction conditions, high yields, environmental benignity, and metal‐free catalyst.
