Coupling of tyramine (I) with p-nitrophenyl isocyanate (II) affords urea (III). Subsequent nitro group reduction with H2 and Pd/C gives amine (IV). Condensation of amine (IV) with ethylene oxide (V) leads to the bis-hydroxyethyl amine (VI). This is finally chlorinated employing SOCl2 in pyridine. Alternatively, amine (IV) is subjected to reductive alkylation with chloroacetaldehyde and NaBH3CN to furnish the target bis-chloroethyl amine. (1,2)
