실험 절차

0.5 mole of α-naphthyl-phenylamine was taken together with 0.53 mole of methyl isocyanate and 0.6 g of di-n-butyl phosphate in 150 ml of toluene. The mixture was warmed at 100° C. for 24 hours, with stirring, and then cooled to 10° C. After the product had been filtered off, washed with 150 ml of cold toluene and dried, 0.4 mole of N-methyl-N'-phenyl-N'-α-naphthyl-urea was obtained. Melting point: 146° C./yield: 80% of theory,
