反応手順
Using the amount of 3-trifluoromethylaniline and N,N-dimethylurea indicated in Example 4, but using the mother liquor from Example 4 instead of pure 1,2,4-trichlorobenzene as the diluent and using 11.4 g (0.25 mol) of dimethylamine, 4.8 g of N-(3-trichloromethylphenyl)-N',N'-dimethylurea, i.e. 83% of theory, having a melting point of 160° to 161° C. and a purity of 99.7% were obtained in the manner described in Example 2.
