74738-17-3 - Production method
2, 3-dichlorobenzaldehyde reacts with dimethyl ether-based triphenylphosphorus to produce (Z) and (E)-2, 3-dichlorophenyl vinyl methyl ether. Then it is acylated with trifluoroacetic acid, and the acylation product is cyclized with potassium aminoacetate to prepare N-fluoroacyl-4-(2, 3-dichlorophenyl) pyrrole-3-trifluoromethyl, The cyclization product uses lithium aluminum hydride to remove the acyl group to obtain 4-(2, 3-dichlorophenyl) pyrrole-3-trifluoromethyl. Finally, it interacts with ammonia to get seed dressing.
