Versuchsvorschrift

0.5 moles of diphenylamine was taken in 150 ml of toluene. 0.53 mole of methyl isocyanate and 1 g of acid compound (see Table 1) were added. The mixture was heated at 100° C. for 8 hours, with stirring, and allowed to cool to room temperature, and the N-methyl-N', N'-dipenylurea formed was filtered off. The urea was washed with 100 ml of cold toluene. For the yield, see Table 1.
