The invention discloses a benzimidazole Schiff base and a synthesis method thereof, which is characterized in that the structural formula of the compound is: Wherein R=hydrogen, C1-C5 alkyl, C1-C5 alkoxy, halogen or nitro. Dissolve 2-aminobenzimidazole and substituted benzaldehyde with a molar ratio of 1: (1-1.5) in an organic solvent, then add a catalyst, heat to 105-115°C under 100-400W microwave radiation, and react for 5-20 minutes. After cooling, filter, wash and recrystallize to obtain benzimidazole Schiff base series derivatives. The invention has short reaction time, high yield and easy industrialization. |
