Synthesis
2-Chloro-5-methyl-1,4-phenylenediamine is prepared by the reaction of o-Quinone and 2-chloro-5-methyl-4-nitroaniline. The steps are as follows:
A reaction vessel was charged with 60 g of isopropyl alcohol, 50 g of water, 37.3 g of 2-chloro-5-methyl-p-nitroaniline, 5 g of potassium hydroxide and 0.6 g of 1,2-benzoquinone, and then the same procedure as in Example 1 was followed, to obtain 28.6 g of 2-chloro-5-methyl-p-phenylenediamine. Yield: 91% Purity determined by G.C. analysis: 99.9%.
