2,5-Dichloro-1,4-benzenediamine Use and Manufacturing

Methods of Manufacturing

Ferulic acid 5.2 gWas methylated with 17.8 g of dimethyl sulfate4.3 g of 3, 4-dimethoxycinnamic acid was prepared, This was converted to pyridine, And acid chloride with thionyl chloride to give 3, 4-dimethoxycinnamic acid chloride.To this was added 1.7 g of 2, 6-dichloro-1, 4-phenylenediamine and 100 ml of monochlorobenzene, And refluxed for 12 hours.After cooling down, The precipitate was filtered off, Washed to recover 1.8 g of a yellow solid.To 1.8 g of the above intermediate, 2.0 g of copper acetate, 6 ml of pyridine and 20 ml of DMF were weighed, refluxed for 12 hours, After cooling down, The precipitate was filtered off, Column purification gave lambda max 404 nm, To obtain the desired product having a melting point of 300 C. or higher.
