A green and efficient mechanochemical method for the synthesis of a series of 2‐arylimidazo[1,2‐a]pyridines was developed using an electrical grinder. I2 catalyzed mechanochemical grinding facilitates the cyclocondensation reaction between various aryl methyl ketones and 2‐aminopyridines to afford 2‐arylimidazo[1,2‐a]pyridines in good yields at ambienttemperature. The method was successfully used
