反応手順
The preparation of, for example, trifluralin is carried out by nitrating 1-trifluoromethyl-4-chlorobenzene with nitric acid in the presence of sulfuric acid to give 1-trifluoromethyl-3,5-dinitro-4-chlorobenzene, from which 2,6-dinitro-4-trifluoromethyl-N,N-dipropylaniline is obtained by amination with the secondary amine, di-n-propylamine. This synthesis can be represented by the following reaction scheme: ##STR1##
