## Abstract A novel synthesis of 1,4‐dialkyl‐5‐aryl‐4‐imidazolin‐2‐ones 3 has been achieved by reaction of α‐bromo ketimines 2 with potassium cyanate in dimethylformamide. The structural assignment of these heterocycles was performed by spectrometric methods, comparison with a known compound and X‐
