実験手順
4-Hydroxy-3-nitrophenylisocyanate (15.5 g), prepared as described by H. Ulrich et al., loc. cit., from 4-amino-2-nitrophenol and phosgene, is added to 100 g of a solution of 29% by weight of dimethylamine in toluene, and the mixture is stirred at room temperature for 2 hours. Evaporation under reduced pressure leaves a residue on recrystallization from water gives N-(4-hydroxy-3-nitrophenyl)-N',N'-dimethylurea, m.pt. 142° C.
