A mixture of 2.0 g. (5.2 mmol.) of 1,3-bis(2-cyano-5-trifluoromethylphenyl)triazene and 1.6 ml. of phenyl isocyanate in 20 ml. of ether is stirred at 25° for 48 hours. The precipitate is collected and recrystallized from ether to give 3-(N-phenylcarbamoyl)-1,3-bis(2-cyano-5-trifluoromethylphenyl)-triazene, m.p. 157°-158°.
