Paragraph 0019-0053, (2020/05/01)
The invention discloses a synthesis method of 6-bromo-4-fluoro-1-isopropyl-2-methyl-1H-benzo[D]imidazole. The method comprises the following steps: (1) adding sodium hydride into a reaction bottle, adding an aprotic solvent into the reaction bottle, and carrying out a constant-temperature stirring reaction; (2) dissolving N-(4-bromo-2,6-difluorophenyl)-N'-isopropylacetamidine in the aprotic solvent, slowly dropwise adding the clarified solution into a reaction bottle, heating the reaction system to 40-100 DEG C, and then carrying out a stirring reaction for 4-10 h; (3) cooling to room temperature after the reaction is completed, adding water to prepare a solution, extracting for three times, mixing organic phases, washing the organic phase with a saturated saline solution once, drying withanhydrous sodium sulfate, and filtering; and (4) concentrating the obtained filtrate, adding n-hexane for dissolving, adding deionized water into the reaction system solution, standing overnight, andfiltering and drying after white crystals are separated out to obtain the 6-bromo-4-fluoro-1-isopropyl-2-methyl-1H-benzo[D]imidazole. The synthesis method is short in reaction time and simple in treatment, the labor cost is saved, and the environmental pollution is reduced.
