Ethylenediamine → 4-nitro-2-methoxy-N-(beta-aminoethyl)aniline

Participants

Reaction Steps

Ethylene diamine is reacted with 2-chloro-5-nitroanisole to form 4-nitro-2-methoxy-N-(β-aminoethyl)aniline which is isolated in the form of its monohydrochloride. This monohydrochloride is reacted with potassium isocyanate to form 4-nitro-2-methoxy-N-(β-ureidoethyl) aniline which is reduced by a sodium hydrosulfite solution to 4-amino-2-methoxy-N-(β-ureidoethyl) aniline.
