Versuchsvorschrift

3.35 g (0.038 mol) of N,N-dimethylurea and 3.38 g (0.025 mol) of 4-isopropylaniline were added with stirring into 20 ml of 1,2,4-trichlorobenzene. The reaction mixture was heated to 205° C., dimethylamine being introduced from 120° C. After 5.5 hours, 8.8 g (0.19 mol) of dimethylamine had been introduced and the reaction was complete.
