Procedure
4-Nitro-[N,N-bis(2-chloroethyl)]aniline (5.0 g; 19.0 mmol) was dissolved in a mixed solvent of 50 ml of ethyl acetate and 25 ml of methanol, followed by the addition of 5.0 ml of 4N hydrochloric acid. Using 10% Pd/C, the reactant was subjected to hydrogenation under normal pressure at room temperature. The Pd/C was filtered off and the solvent was distilled out. The residue was crystallized from ethanol-ethyl ether, whereby 4.1 g (15.2 mmol) of the title compound was obtained (yield: 80%). m.p. 230°-233° C.
