Reaction Steps
1,3-Di-(4-nitrophenyl)urea was prepared by the dropwise addition of a solution of p-nitrophenylisocyanate (16.4 g, 0.1 mole) in dimethyl formamide (150 ml) to a solution of p-nitroaniline (13.8 g, 0.1 mole) in dimethylformamide (130 ml) at 4° C. 1,3-Di-(4-nitrophenyl)urea precipitated slowly as a yellow solid.
