실험 절차

22.9 g (0.1 mol) of 3,5-bis-trifluoromethyl-aniline were dissolved in 150 ml of dry toluene. 11.9 g (0.1 mol) of chloroacetyl isocyanate in 50 ml of dry toluene were added. The mixture was stirred at 50° C. for 1 hour and then cooled to room temperature. The product which had precipitated was filtered off and rinsed with toluene/ligroin 1:2 and then dried. 26 g (74.5% of theory) of N-(3,5-bis-trifluoromethylphenyl)-N'-(chloroacetyl)-urea with a melting point of 170° C. were thus obtained.
