| titleOfInvention | N under a kind of microwave radiation, the method for the thio formyl chloride derivatives catalysis synthesizing benzimidazole derivative of N- dimethylamino |
| abstract | The present invention discloses a kind of method that benzimidizole derivatives are catalyzed and synthesized under microwave radiation, catalyst cuprous iodide, cocatalyst sodium hydroxide and the o-phenylenediamine and its derivative of catalytic amount are added in the reaction vessel, N, the thio formyl chlorine derivative of N- dimethylamino is as raw material, pyridine solvent is placed in microwave reaction instrument and reacts under certain temperature and power, after a certain period of time, it is concentrated under reduced pressure, product passes through column chromatographic purifying.The present invention is that a kind of raw material is novel, easy to operate, efficiently prepares the method for benzimidizole derivatives.Compared with prior art, the method reaction speed is obviously accelerated compared under conventional heating, and reaction condition is mild, easy to operate, yield is high, safety, low in cost, environmental protection； 。 |
