Procedure

1.1 A solution of 15.35 g of 4-chlorophenyl isocyanate in 50 ml of THF is added to a solution of 9.83 g of phenylhydrazine in 100 ml of THF under a nitrogen atmosphere, and the mixture is refluxed for 2 hours. Conventional work-up gives 25.1 g of N-(4-chlorophenylaminocarbonyl)-N′-phenylhydrazine(“AA”), El 277, m.p. 187-189.
