摘　　要： 2-(p-dimethylamino)-benzimidazole was synthesized by the reaction of o-phenylenediamine(I)with p-dimethylaminobenaldehyde(II)which was accelerated by microwave irradiation and ethyl alcohol as solvent.The optimal conditions were as follow:n(II)∶n(I)=1.3∶1,the temperature of microwave irradiation was 68℃,the time of microwave irradiation was 20 min.Under the optimal condition,the highest yield of the title compound was 79.6%.The samples synthesized were characterized by melting point determination,IR spectrogram,1HNMR spectra. 2- （p-dimethylamino） -benzimidazole was synthesized by the reaction of o-phenylenediamine （I） with p-dimethylaminobenaldehyde（H） which was accelerated by microwave irradiation and ethyl alcohol as solvent. The optimal conditions were as follow：n （H） ：n（I） = 1.3：1 ,the temperature of microwave irradiation was 68℃ ,the time of microwave irradiation was 20 min. Under the optimal condition, the highest yield of the title compound was 79.6%. The samples synthesized were characterized by melting point determination, IR spectrogram, ^1HNMR spectra.
