[Preparation]

To a refluxing solution of triphosgene in 1,2-dichloroethane, a solution of tris(p-aminophenyl)amine in 1,2- dichloroethane was added dropwise and the mixture was heated to reflux under dry nitrogen. Tris(p-isocyanatophenyl)amine was obtained in 63% yield after purification by recrystallization from diethyl ether; mp 148 °C.
