Reaction Steps
4-nitro-2-methyl-N-(β-aminoethyl) aniline monohydrochloride is obtained by reacting ethylene diamine with 2-chloro-5-nitro-toluene. This monohydrochloride is then reacted with potassium isocyanate to produce 4-nitro-2-methyl-N-(β-ureidoethyl) aniline, which is reduced with hydrazine and Raney's nickel to 4-amino-2-methyl-N-(β-ureidoethyl) aniline.
