Thereafter, the reaction mixture was filtered, the filter cake was washed with ethyl acetate, and the filtrate was evaporated in vacuo, leaving 10 gm of an oil which was used as the starting material in Example 11 without further purification. It was identified to be N-(3-chloro-phenyl)-N'-(4-methyl-phenyl)-ethylenediamine.
