  • Benzimidazole compound and preparation method thereof
    Patent number: 10787420
    Abstract: A benzimidazole compound and a preparation method thereof. Various substituted benzimidazoles are synthesized by a SN2 reaction and a cyclization reaction. Namely, o-fluorinated aryl-N,N-dimethyl-formamidine and primary amine are subjected to an cyclization by a one-pot reaction, wherein a fluorine atom is substituted by an amino, and then dimethylamine is eliminated, thus forming the product. The method does not require the use of any metal catalyst and/or any toxic reagent, and has a specific selectivity. No isomer exists in the reaction product.
    Type: Grant
    Filed: September 28, 2017
    Date of Patent: September 29, 2020
    Assignees: SHANDONG ENGINEERING AND TECHNOLOGY INSTITUTE OF LUNAN COAL CHEMICAL ENGINEERING, ZAOZHUANG UNIVERSITY, SHANDONG JITIAN AROMA CHEMICAL CO LTD, Asset (Suzhou) Pharma Co., Ltd.
