N-methylpyrrolidine was successfully synthesized in a aqueous medium by using methylamine and 1,4-dibromobutane in the presence o f catalyst K2CO3 at a moderated temperature. Here, N-methylpyrrolidine was firstly synthesized via the green chemistry process, in which both the water solvent and potassium carbo nate catalyst were inexpensive and environmentally friendly. Also, the reaction temper ature was quite moderated at 90 C. As a result, the current synthesis process was highly po tential to implement in practice. Since the product yield directly depended on the operating co nditions, the catalysts, temperature, ratio of reactants and solvent would be critical factors. In the present study, the structure of Nmethylpyrrolidine product was confirmed by using th e IR, H-NMR, C-NMR and Gas Chromatography-Mass spectroscopy (GC-MS) .
