A mixture of 4,5-dichlorophenylendiamine (4 g, 22.6 mmol) and methyl 4-formylbenzoate (3.68, 22.6 mmol) in nitrobenzene (35 ml) was heated at 140° C. for 30 h. After cooling, the mixture was diluted with n-hexane (150 ml) and stirred for 1 h. The solid was filtered obtaining 5 g of the title compound (yield 68.9%) as a brown powder, mp=240–250° C.
