A simple method for microwave-assisted amination of 3-bromo-2-chloropyridine with various substituted aminoethanols is described. The reaction was carried out under microwave irradiation conditions (at 180 degrees C for 1-2 h) and the result was superior in terms of conversion and yield when compared to that of the corresponding conventional heating conditions.
