2-aminothiazoles derivatives and method of preparation thereof using super-paramagnetic iron oxide nanoparticles (spions)

A method of making a pyrazole compound includes mixing a diazonium salt with a reactant in the presence of a solvent, thereby coupling a diazo group of the diazonium salt to an α-carbon atom of the reactant to form a reaction intermediate having a formula of (I) or (II); mixing the reaction intermediate and hydrazine in the presence of a superparamagnetic iron oxide nanoparticles catalyst thereby cyclizing the hydrazine with an ester group of the reaction intermediate to form the pyrazole compound having a formula of (III) or (IV).
