flufenoxoron - Preparation Method
Open Data Verified Data
2-fluoro-4-hydroxyaniline was prepared from O-fluoronitrobenzene and reacted with 3,4-= chlorotrifluorotoluene in the presence of potassium hydroxide in dimethyl sulfoxide, 4 (4-fluoromethyl -2-chlorophenoxy) a 2 fluoroaniline was prepared. In addition, 2,6-= fluorobenzoyl isocyanate was prepared by reacting 2,6-= fluorobenzoyl amide with oxalyl chloride in dichloromethane. Flumizide was synthesized by addition of 2,6-fluorobenzoyl isocyanate with 4-4-(4-fluoromethyl-2-chlorophenoxy)-2-fluoroaniline obtained above.
