Abstract:In this paper, 2-bromo-4-fluoroacetanilide was obtained by acetylation and brominated using 4-fluoroaniline as the starting material. Then this obtained intermediate reacted with 3,4-dichlorophenylboronic by Suzuki coupling followed by deacetylation using thionyl chloride to give 2-(3,4-dichlorophenyl)-4-fluoroaniline. The reaction conditions were studied and the total yield was up to 66.3%. The structure was confirmed by MS and 1H NMR. |
Key words:bixafen; Suzuki coupling; 2-(3,4-dichlorophenyl)-4-fluoroaniline |
