1,2‐Diaryl‐4‐phenylmethylene‐2‐imidazolin‐5‐ones were obtained by the interaction of primary amines with 2‐phenyl‐4‐phenylmethylene‐2‐oxazolin‐5‐one using acidic alumina or montmorillonite K10 clay under microwave irradiation (MWI). The same reaction over basic alumina gave arylamides of α‐arylamido‐β‐arylacrylic acids in good yield. Usage of acidic alumina for cyclization gave better results in comparison with clay. This procedure highlights the versatility of various solid supports.
