Microwave assisted solvent-free synthesis of N-phenyl-4-(pyridin-4-yl)thiazoles and their drug-likeness studies

A new, fast and solvent-free method is offers to synthesize thiazoles by condensation of 4-bromoacetylpyridine with substituted N-phenylthiourea under microwave irradiation. This approach delivers good to excellent yields of thiazoles within 5 min without using any catalyst and allows various functionalities. In comparison to the traditional heating approach, this method enables for the synthesis of different thiazole analogues with several advantages. In compliance with the Lipinski rule of five, the synthesized analogues demonstrated drug-like characteristics.
