Methyl 3-({3-[(tert-butoxycarbonyl)amino]propyl}amino)-4-nitrobenzoate (10.2 g) in solution in a mixture of ethyl acetate/methanol 3:1 (300 ml), and 10% palladium on carbon (1.02 g) are introduced into an autoclave. After stirring for 4 hours under a hydrogen atmosphere (3 bar) at a temperature of approximately 20° C., the catalyst is eliminated by filtration on celite and the filtrate is concentrated under reduced pressure at 40° C. in order to produce the expected compound in the form of an oil (7.75 g; 83% yield).
