Benzoxazole, important to pharmaceutical advancements, was synthesized through the condensation reaction of benzaldehyde and 2-aminophenol under acidic conditions and being characterized using 1H-NMR spectroscopy. This project revealed an efficient method for 2-phenylbenzoxazole synthesis using various acidic catalytic system. A solid catalyst mixture of p-toluenesulfonic acid and silica gel (TsOH-SiO2) in xylene solvent at 140°C generated the product at 69.66% yield.
